______________________________________________________________________________ 1) problem description, brief discussion The Apache daemon is running on most of the web-servers used in the Internet today. The Red Hat ASF Security-Team and the Swedish IT Incident Center within the National Post and Telecom Agency (SITIC) have found a bug in apache2 each. The first vulnerability appears in the apr_uri_parse() function while handling IPv6 addresses. The affected code passes a negative length argument to the memcpy() function. On BSD systems this can lead to remote command execution due to the nature of the memcpy() implementation. On Linux this bug will result in a remote denial-of-service condition. The second bug is a local buffer overflow that occurs while expanding ${ENVVAR} in the .htaccess and httpd.conf file. Both files are not writeable by normal user by default. 2) solution/workaround There is no known workaround. 3) special instructions and notes After the new apache2 packages have been installed you have to restart the apache2 daemon by executing the following command as root: /usr/sbin/rcapache2 restart 4) package location and checksums 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 apply 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/apache2-2.0.49-27.14.i586.rpm

Pending vulnerabilities in SUSE Distributions and Workarounds: - samba This version fixes several bugs in the Samba suite including two denial-of-service (DoS) Vulnerabilities. Microsoft Windows XP clients with installed Service Pack 2 crash the Samba (smbd) process while printing. Using macros in the smb.conf 'log file' statement might lead to an infinite recursion. A wrong counter and pointer handling in samba-vscan leads to a crash of the Samba (smbd) process sometimes. A DoS bug in smbd may allow an unauthenticated user to cause smbd to spawn new processes, each one entering an infinite loop. After sending a sufficient amount of packets it is possible to exhaust the memory resources on the server. This issue is known as CAN-2004-0807. A DoS bug in nmbd may allow an attacker to remotely crash the nmbd daemon. This issue is known as CAN-2004-0808. New packages are available on our FTP servers. - a2ps This update fixes the handling of filenames that include shell meta- characters. Without this patch it was possible to execute shell commands via a2ps by providing a filename that includes meta- characters as an argument. New packages are available on our FTP servers. - mozilla We are in the process of releasing updates for mozilla (and related browsers), fixing various issues: CAN-2004-0597, CAN-2004-0718, CAN-2004-0722, CAN-2004-0757, CAN-2004-0758, CAN-2004-0759, CAN-2004- 0760, CAN-2004-0761, CAN-2004-0762, CAN-2004-0763, CAN-2004-0764 and CAN-2004-0765. We will give you concrete details in a separate mozilla advisory when the updates are available. - mc The console filesystem browser mc was found vulnerable to various meta-char attacks in the extfs perl and shell scripts. These bugs can be exploited by providing a malformed archive file to a victim user to execute shell commands with her/his privileges. (CAN-2004-0494) New packages will be available soon. - squid Certain malformed NTLMSSP packets can crash the NTLM helpers provided by Squid (CAN-2004-0832). New packages will be available soon. - gtk2 This update fixes three vulnerabilities found in the XPM loader code of the GTK Library. They are registered as: + CAN-2004-0782 Heap-based overflow in pixbuf_create_from_xpm + CAN-2004-0783 Stack-based overflow in xpm_extract_color + CAN-2004-0788 icon loader integer overflow. New packages will be available soon. - gaim This security update fixes four security issues which are registered as: + CAN-2004-0754 An integer overflow in the groupware message handler exists in Gaim. + CAN-2004-0784 A shell escape vulnerability in the handling of smiley theme tar- ball filenames could lead to arbitrary command execution. + CAN-2004-0785 Buffer overflows in Gaim could lead to a denial of service or arbitrary code execution. Additionally a buffer overflow in the URL parsing code of gaim is fixed. This bug let to remote system compromise with the privileges of the user running gaim. - nessus The nessus-adduser creates temporary files in $TMPDIR in an insecure manner. New packages will be available soon. ______________________________________________________________________________ 6) standard appendix: authenticity verification, additional information - Package authenticity verification: SUSE update packages are available on many mirror ftp servers all over the world. While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other 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 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 show proof of the authenticity of the package. We disrecommend to subscribe 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 authenticity 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 rpm package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of this 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.gpg) 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>. For general information or the frequently asked questions (faq) send mail to: <suse-security-info@suse.com> or <suse-security-faq@suse.com> respectively. ==================================================================== SUSE's security contact is <security@suse.com> or <security@suse.de>.

______________________________________________________________________________ 1) problem description, brief discussion The Apache daemon is running on most of the web-servers used in the Internet today. The Red Hat ASF Security-Team and the Swedish IT Incident Center within the National Post and Telecom Agency (SITIC) have found a bug in apache2 each. The first vulnerability appears in the apr_uri_parse() function while handling IPv6 addresses. The affected code passes a negative length argument to the memcpy() function. On BSD systems this can lead to remote command execution due to the nature of the memcpy() implementation. On Linux this bug will result in a remote denial-of-service condition. The second bug is a local buffer overflow that occurs while expanding ${ENVVAR} in the .htaccess and httpd.conf file. Both files are not writeable by normal user by default. 2) solution/workaround There is no known workaround. 3) special instructions and notes After the new apache2 packages have been installed you have to restart the apache2 daemon by executing the following command as root: /usr/sbin/rcapache2 restart 4) package location and checksums 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 apply 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/apache2-2.0.49-27.14.i586.rpm

Pending vulnerabilities in SUSE Distributions and Workarounds: - samba This version fixes several bugs in the Samba suite including two denial-of-service (DoS) Vulnerabilities. Microsoft Windows XP clients with installed Service Pack 2 crash the Samba (smbd) process while printing. Using macros in the smb.conf 'log file' statement might lead to an infinite recursion. A wrong counter and pointer handling in samba-vscan leads to a crash of the Samba (smbd) process sometimes. A DoS bug in smbd may allow an unauthenticated user to cause smbd to spawn new processes, each one entering an infinite loop. After sending a sufficient amount of packets it is possible to exhaust the memory resources on the server. This issue is known as CAN-2004-0807. A DoS bug in nmbd may allow an attacker to remotely crash the nmbd daemon. This issue is known as CAN-2004-0808. New packages are available on our FTP servers. - a2ps This update fixes the handling of filenames that include shell meta- characters. Without this patch it was possible to execute shell commands via a2ps by providing a filename that includes meta- characters as an argument. New packages are available on our FTP servers. - mozilla We are in the process of releasing updates for mozilla (and related browsers), fixing various issues: CAN-2004-0597, CAN-2004-0718, CAN-2004-0722, CAN-2004-0757, CAN-2004-0758, CAN-2004-0759, CAN-2004- 0760, CAN-2004-0761, CAN-2004-0762, CAN-2004-0763, CAN-2004-0764 and CAN-2004-0765. We will give you concrete details in a separate mozilla advisory when the updates are available. - mc The console filesystem browser mc was found vulnerable to various meta-char attacks in the extfs perl and shell scripts. These bugs can be exploited by providing a malformed archive file to a victim user to execute shell commands with her/his privileges. (CAN-2004-0494) New packages will be available soon. - squid Certain malformed NTLMSSP packets can crash the NTLM helpers provided by Squid (CAN-2004-0832). New packages will be available soon. - gtk2 This update fixes three vulnerabilities found in the XPM loader code of the GTK Library. They are registered as: + CAN-2004-0782 Heap-based overflow in pixbuf_create_from_xpm + CAN-2004-0783 Stack-based overflow in xpm_extract_color + CAN-2004-0788 icon loader integer overflow. New packages will be available soon. - gaim This security update fixes four security issues which are registered as: + CAN-2004-0754 An integer overflow in the groupware message handler exists in Gaim. + CAN-2004-0784 A shell escape vulnerability in the handling of smiley theme tar- ball filenames could lead to arbitrary command execution. + CAN-2004-0785 Buffer overflows in Gaim could lead to a denial of service or arbitrary code execution. Additionally a buffer overflow in the URL parsing code of gaim is fixed. This bug let to remote system compromise with the privileges of the user running gaim. - nessus The nessus-adduser creates temporary files in $TMPDIR in an insecure manner. New packages will be available soon. ______________________________________________________________________________ 6) standard appendix: authenticity verification, additional information - Package authenticity verification: SUSE update packages are available on many mirror ftp servers all over the world. While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other 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 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 show proof of the authenticity of the package. We disrecommend to subscribe 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 authenticity 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 rpm package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of this 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.gpg) 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>. For general information or the frequently asked questions (faq) send mail to: <suse-security-info@suse.com> or <suse-security-faq@suse.com> respectively. ==================================================================== SUSE's security contact is <security@suse.com> or <security@suse.de>. The <security@suse.de> public key is listed below. ==================================================================== ______________________________________________________________________________ The information in this advisory may be distributed or reproduced, provided that the advisory is not modified in any way.
