1) problem description, brief discussion, solution, upgrade information Multiple security vulnerabilities are being addressed with this security update of the Linux kernel. Kernel memory access vulnerabilities are fixed in the e1000, decnet, acpi_asus, alsa, airo/WLAN, pss and mpu401 drivers. These vulnerabilities can lead to kernel memory read access, write access and local denial of service conditions, resulting in access to the root account for an attacker with a local account on the affected system. Missing Discretionary Access Control (DAC) checks in the chown(2) system call allow an attacker with a local account to change the group ownership of arbitrary files, which leads to root privileges on affected systems. It is specific to kernel version 2.6 based systems such as the SUSE Linux 9.1 product, that only local shell access is needed to exploit this vulnerability. An interesting variant of the missing checks is that the ownership of files in the /proc filesystem can be altered, while the changed ownership still does not allow the files to be accessed as a non-root user for to be able to exploit the vulnerability. Systems that are based on a version 2.4 kernel are not vulnerable to the /proc weakness, and exploitation of the weakness requires the use of the kernel NFS server (knfsd). If the knfsd NFS server is not activated (it is off by default), the vulnerability is not exposed. These issues related to the chown(2) system call have been discovered by Michael Schroeder and Ruediger Oertel, both SUSE LINUX. The only network-related vulnerability fixed with the kernel updates that are subject to this announcement affect the SUSE Linux 9.1 distribution only, as it is based on a 2.6 kernel. Found and reported to bugtraq by Adam Osuchowski and Tomasz Dubinski, the vulnerability allows a remote attacker to send a specially crafted TCP packet to a vulnerable system, causing that system to stall if it makes use of TCP option matching netfilter rules. In some rare configurations of the SUSE Linux 9.1 distribution, some users have experienced stalling systems during system startup. These problems are fixed with this kernel update. SPECIAL INSTALL INSTRUCTIONS: ======================= ======= For the impatient: Run YOU (Yast2 Online Update, command "yast2 online_update" as root) to install the updates (semi) automatically, if you have a SUSE Linux 8.1 and newer system. For those who wish to install their kernel updates manually and for those who use a SUSE Linux 8.0 system: The following paragraphs will guide you through the installation process in a step-by-step fashion. The character sequence "****" marks the beginning of a new paragraph. In some cases, the steps outlined in a particular paragraph may or may not be applicable to your situation. Therefore, please make sure to read through all of the steps below before attempting any of these procedures. All of the commands that need to be executed are required to be run as the superuser (root). Each step relies on the steps before it to complete successfully. **** Step 1: Determine the needed kernel type Please use the following command to find the kernel type that is installed on your system: rpm -qf /boot/vmlinuz Following are the possible kernel types (disregard the version and build number following the name separated by the "-" character) k_deflt # default kernel, good for most systems. k_i386 # kernel for older processors and chipsets k_athlon # kernel made specifically for AMD Athlon(tm) family proces sors k_psmp # kernel for Pentium-I dual processor systems k_smp # kernel for SMP systems (Pentium-II and above) k_smp4G # kernel for SMP systems which supports a maximum of 4G of RAM kernel-64k-pagesize kernel-bigsmp kernel-default kernel-smp **** Step 2: Download the package for your system Please download the kernel RPM package for your distribution with the name as indicated by Step 1. The list of all kernel rpm packages is appended below. Note: The kernel-source package does not contain a binary kernel in bootable form. Instead, it contains the sources that the binary kernel rpm packages are created from. It can be used by administrators who have decided to build their own kernel. Since the kernel-source.rpm is an installable (compiled) package that contains sources for the linux kernel, it is not the source RPM for the kernel RPM binary packages. The kernel RPM binary packages for the distributions can be found at th e locations below ftp://ftp.suse.com/pub/suse/i386/update/. 8.0/images/ 8.1/rpm/i586 8.2/rpm/i586 9.0/rpm/i586 9.1/rpm/i586 After downloading the kernel RPM package for your system, you should verify the authenticity of the kernel rpm package using the methods as listed in section 3) of each SUSE Security Announcement. **** Step 3: Installing your kernel rpm package Install the rpm package that you have downloaded in Steps 3 or 4 with the command rpm -Uhv --nodeps --force <K_FILE.RPM> where <K_FILE.RPM> is the name of the rpm package that you downloaded. Warning: After performing this step, your system will likely not be able to boot if the following steps have not been fully followed. If you run SUSE LINUX 8.1 and haven't applied the kernel update (SUSE-SA:2003:034), AND you are using the freeswan package, you also need to update the freeswan rpm as a dependency as offered by YOU (YaST Online Update). The package can be downloaded from ftp://ftp.suse.com/pub/suse/i386/update/8.1/rpm/i586/ **** Step 4: configuring and creating the initrd The initrd is a ramdisk that is loaded into the memory of your system together with the kernel boot image by the bootloader. The kernel uses the content of this ramdisk to execute commands that must be run before the kernel can mount its actual root filesystem. It is usually used to initialize SCSI drivers or NIC drivers for diskless operation. The variable INITRD_MODULES in /etc/sysconfig/kernel determines which kernel modules will be loaded in the initrd before the kernel has mounted its actual root filesystem. The variable should contain your SCSI adapter (if any) or filesystem driver modules. With the installation of the new kernel, the initrd has to be re-packed with the update kernel modules. Please run the command mk_initrd as root to create a new init ramdisk (initrd) for your system. On SuSE Linux 8.1 and later, this is done automatically when the RPM is installed. **** Step 5: bootloader If you run a SUSE LINUX 8.x, SLES8, or SUSE LINUX 9.x system, there are two options: Depending on your software configuration, you have either the lilo bootloader or the grub bootloader installed and initialized on your system. The grub bootloader does not require any further actions to be performed after the new kernel images have been moved in place by the rpm Update command. If you have a lilo bootloader installed and initialized, then the lilo program must be run as root. Use the command grep LOADER_TYPE /etc/sysconfig/bootloader to find out which boot loader is configured. If it is lilo, then you must run the lilo command as root. If grub is listed, then your system does not require any bootloader initialization. Warning: An improperly installed bootloader may render your system unbootable. **** Step 6: reboot If all of the steps above have been successfully completed on your system, then the new kernel including the kernel modules and the initrd should be ready to boot. The system needs to be rebooted for the changes to become active. Please make sure that all steps have completed, then reboot using the command shutdown -r now or init 6 Your system should now shut down and reboot with the new kernel. There is no workaround known. Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, install the package using the command "rpm -Fhv file.rpm" to appl y the update. Our maintenance customers are being notified individually. The packages are being offered to install from the maintenance web. x86 Platform: SUSE Linux 9.1: ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/kernel-default-2.6 .5-7.95.i586.rpm

While this service is considered valuable and important to the free and open source software community, many users wish to be certain as to be the origin of the package and its content before installing the package. There are two independent verification methods that can be used to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum <name-of-the-file.rpm> after you have downloaded the file from a SUSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security@suse.de), the checksums offer proof of the authenticity of the package. We recommend against subscribing to security lists which cause the email message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticit y of an rpm package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, where <file.rpm> is the filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an un-installed rp m package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of th is key must be installed by the gpg program in the directory ~/.gnupg/ under the user's home directory who performs the signature verification (usually root). You can import the key that is used by SUSE in rpm packages for SUSE Linux by saving this announcement to a file ("announcement.txt") and running the command (do "su -" to be root): gpg --batch; gpg < announcement.txt | gpg --import SUSE Linux distributions version 7.1 and thereafter install the key "build@suse.de" upon installation or upgrade, provided that the package gpg is installed. The file containing the public key is placed at the top-level directory of the first CD (pubring.gp g) and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de . - SUSE runs two security mailing lists to which any interested party may subscribe: suse-security@suse.com - general/linux/SUSE security discussion.

1) problem description, brief discussion, solution, upgrade information Multiple security vulnerabilities are being addressed with this security update of the Linux kernel. Kernel memory access vulnerabilities are fixed in the e1000, decnet, acpi_asus, alsa, airo/WLAN, pss and mpu401 drivers. These vulnerabilities can lead to kernel memory read access, write access and local denial of service conditions, resulting in access to the root account for an attacker with a local account on the affected system. Missing Discretionary Access Control (DAC) checks in the chown(2) system call allow an attacker with a local account to change the group ownership of arbitrary files, which leads to root privileges on affected systems. It is specific to kernel version 2.6 based systems such as the SUSE Linux 9.1 product, that only local shell access is needed to exploit this vulnerability. An interesting variant of the missing checks is that the ownership of files in the /proc filesystem can be altered, while the changed ownership still does not allow the files to be accessed as a non-root user for to be able to exploit the vulnerability. Systems that are based on a version 2.4 kernel are not vulnerable to the /proc weakness, and exploitation of the weakness requires the use of the kernel NFS server (knfsd). If the knfsd NFS server is not activated (it is off by default), the vulnerability is not exposed. These issues related to the chown(2) system call have been discovered by Michael Schroeder and Ruediger Oertel, both SUSE LINUX. The only network-related vulnerability fixed with the kernel updates that are subject to this announcement affect the SUSE Linux 9.1 distribution only, as it is based on a 2.6 kernel. Found and reported to bugtraq by Adam Osuchowski and Tomasz Dubinski, the vulnerability allows a remote attacker to send a specially crafted TCP packet to a vulnerable system, causing that system to stall if it makes use of TCP option matching netfilter rules. In some rare configurations of the SUSE Linux 9.1 distribution, some users have experienced stalling systems during system startup. These problems are fixed with this kernel update. SPECIAL INSTALL INSTRUCTIONS: ======================= ======= For the impatient: Run YOU (Yast2 Online Update, command "yast2 online_update" as root) to install the updates (semi) automatically, if you have a SUSE Linux 8.1 and newer system. For those who wish to install their kernel updates manually and for those who use a SUSE Linux 8.0 system: The following paragraphs will guide you through the installation process in a step-by-step fashion. The character sequence "****" marks the beginning of a new paragraph. In some cases, the steps outlined in a particular paragraph may or may not be applicable to your situation. Therefore, please make sure to read through all of the steps below before attempting any of these procedures. All of the commands that need to be executed are required to be run as the superuser (root). Each step relies on the steps before it to complete successfully. **** Step 1: Determine the needed kernel type Please use the following command to find the kernel type that is installed on your system: rpm -qf /boot/vmlinuz Following are the possible kernel types (disregard the version and build number following the name separated by the "-" character) k_deflt # default kernel, good for most systems. k_i386 # kernel for older processors and chipsets k_athlon # kernel made specifically for AMD Athlon(tm) family proces sors k_psmp # kernel for Pentium-I dual processor systems k_smp # kernel for SMP systems (Pentium-II and above) k_smp4G # kernel for SMP systems which supports a maximum of 4G of RAM kernel-64k-pagesize kernel-bigsmp kernel-default kernel-smp **** Step 2: Download the package for your system Please download the kernel RPM package for your distribution with the name as indicated by Step 1. The list of all kernel rpm packages is appended below. Note: The kernel-source package does not contain a binary kernel in bootable form. Instead, it contains the sources that the binary kernel rpm packages are created from. It can be used by administrators who have decided to build their own kernel. Since the kernel-source.rpm is an installable (compiled) package that contains sources for the linux kernel, it is not the source RPM for the kernel RPM binary packages. The kernel RPM binary packages for the distributions can be found at th e locations below ftp://ftp.suse.com/pub/suse/i386/update/. 8.0/images/ 8.1/rpm/i586 8.2/rpm/i586 9.0/rpm/i586 9.1/rpm/i586 After downloading the kernel RPM package for your system, you should verify the authenticity of the kernel rpm package using the methods as listed in section 3) of each SUSE Security Announcement. **** Step 3: Installing your kernel rpm package Install the rpm package that you have downloaded in Steps 3 or 4 with the command rpm -Uhv --nodeps --force <K_FILE.RPM> where <K_FILE.RPM> is the name of the rpm package that you downloaded. Warning: After performing this step, your system will likely not be able to boot if the following steps have not been fully followed. If you run SUSE LINUX 8.1 and haven't applied the kernel update (SUSE-SA:2003:034), AND you are using the freeswan package, you also need to update the freeswan rpm as a dependency as offered by YOU (YaST Online Update). The package can be downloaded from ftp://ftp.suse.com/pub/suse/i386/update/8.1/rpm/i586/ **** Step 4: configuring and creating the initrd The initrd is a ramdisk that is loaded into the memory of your system together with the kernel boot image by the bootloader. The kernel uses the content of this ramdisk to execute commands that must be run before the kernel can mount its actual root filesystem. It is usually used to initialize SCSI drivers or NIC drivers for diskless operation. The variable INITRD_MODULES in /etc/sysconfig/kernel determines which kernel modules will be loaded in the initrd before the kernel has mounted its actual root filesystem. The variable should contain your SCSI adapter (if any) or filesystem driver modules. With the installation of the new kernel, the initrd has to be re-packed with the update kernel modules. Please run the command mk_initrd as root to create a new init ramdisk (initrd) for your system. On SuSE Linux 8.1 and later, this is done automatically when the RPM is installed. **** Step 5: bootloader If you run a SUSE LINUX 8.x, SLES8, or SUSE LINUX 9.x system, there are two options: Depending on your software configuration, you have either the lilo bootloader or the grub bootloader installed and initialized on your system. The grub bootloader does not require any further actions to be performed after the new kernel images have been moved in place by the rpm Update command. If you have a lilo bootloader installed and initialized, then the lilo program must be run as root. Use the command grep LOADER_TYPE /etc/sysconfig/bootloader to find out which boot loader is configured. If it is lilo, then you must run the lilo command as root. If grub is listed, then your system does not require any bootloader initialization. Warning: An improperly installed bootloader may render your system unbootable. **** Step 6: reboot If all of the steps above have been successfully completed on your system, then the new kernel including the kernel modules and the initrd should be ready to boot. The system needs to be rebooted for the changes to become active. Please make sure that all steps have completed, then reboot using the command shutdown -r now or init 6 Your system should now shut down and reboot with the new kernel. There is no workaround known. Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, install the package using the command "rpm -Fhv file.rpm" to appl y the update. Our maintenance customers are being notified individually. The packages are being offered to install from the maintenance web. x86 Platform: SUSE Linux 9.1: ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/kernel-default-2.6 .5-7.95.i586.rpm

___________________________________________________________________________ ___ 2) Pending vulnerabilities in SUSE Distributions and Workarounds: - icecast The icecast service is vulnerable to a remote denial-of-service attack. Update packages will be available soon. - sitecopy The sitecopy package includes a vulnerable version of the neon library (CAN-2004-0179, CAN-2004-0398). Update packages will be available soon. - cadaver The cadaver package includes a vulnerable version of the neon library (CAN-2004-0179, CAN-2004-0398). Update packages will be available soon. - OpenOffice_org The OpenOffice_org package includes a vulnerable version of the neon library (CAN-2004-0179, CAN-2004-0398). Update packages will be available soon. - tripwire A format string bug in tripwire can be exploited locally to gain root permissions. New packages are available. - postgresql A buffer overflow in psqlODBC could be exploited to crash the application using it. E.g. a PHP script that uses ODBC to access a PostgreSQL database can be utilized to crash the surrounding Apache web-server. Other parts of PostgreSQL are not affected. New packages are available. - XDM/XFree86 This update resolves random listening to ports by XDM that allows to connect via the XDMCP. SUSE LINUX 9.1 is affected only. New packages are available. - mod_proxy A buffer overflow can be triggered by malicious remote servers that return a negative Content-Length value. This vulnerability can be used to execute commands remotely New packages are available. - freeswan A bug in the certificate chain authentication code could allow an attacker to authenticate any host against a FreeS/WAN server by presenting specially crafted certificates wrapped in a PKCS#7 file. The packages are currently being tested and will be available soon. - ipsec-tools The racoon daemon which is responsible for handling IKE messages fails to reject invalid or self-signed X.509 certificates which allows for man-in-the-middle attacks on IPsec tunnels established via racoon. The packages are currently being tested and will be available soon. - less This update fixes a possible symlink attack in lessopen.sh. The attack can be executed by local users to overwrite arbitrary files with the privileges of the user running less. New packages are available. - libpng This update adds a missing fix for CAN-2002-1363. New packages are available. - pavuk This update fixes a remotely exploitable buffer overflow in pavuk. Thanks to Ulf Harnhammar for reporting this to us. New packages are available. - kdebase3 This update fixes a possible attack on tmp files created at the first login of a user using KDE or at the first time running a KDE application. This bug can be exploited locally to overwrite arbitrary files with the privilege of the victim user. Just affects SUSE LINUX 9.1 New packages are available. ___________________________________________________________________________ ___ 3) standard appendix: authenticity verification, additional information - Package authenticity verification: SUSE update packages are available on many mirror ftp servers around the world. While this service is considered valuable and important to the free and open source software community, many users wish to be certain as to be the origin of the package and its content before installing the package. There are two independent verification methods that can be used to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum <name-of-the-file.rpm> after you have downloaded the file from a SUSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security@suse.de), the checksums offer proof of the authenticity of the package. We recommend against subscribing to security lists which cause the email message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticit y of an rpm package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, where <file.rpm> is the filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an un-installed rp m package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of th is key must be installed by the gpg program in the directory ~/.gnupg/ under the user's home directory who performs the signature verification (usually root). You can import the key that is used by SUSE in rpm packages for SUSE Linux by saving this announcement to a file ("announcement.txt") and running the command (do "su -" to be root): gpg --batch; gpg < announcement.txt | gpg --import SUSE Linux distributions version 7.1 and thereafter install the key "build@suse.de" upon installation or upgrade, provided that the package gpg is installed. The file containing the public key is placed at the top-level directory of the first CD (pubring.gp g) and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de . - SUSE runs two security mailing lists to which any interested party may subscribe: suse-security@suse.com - general/linux/SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an email to <suse-security-subscribe@suse.com>. suse-security-announce@suse.com - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an email to <suse-security-announce-subscribe@suse.com>.
