______________________________________________________________________________

1) Solved Security Vulnerabilities

To avoid flooding mailing lists with SUSE Security Announcements for minor
issues, SUSE Security releases weekly summary reports for the low profile
vulnerability fixes. The SUSE Security Summary Reports do not list md5 sums
or download URLs like the SUSE Security Announcements that are released for
more severe vulnerabilities.

Fixed packages for the following incidents are already available on our FTP
server and via the YaST Online Update.

- net-snmp denial of service problem

A old denial of service problem in net-snmp was fixed which could
be triggered by a packet containing a single byte. (CVE-2005-2177)

The fix for this was forgotten for SUSE Linux 9.3 and 10.0 and was
released now.

- vim modeline code execution problem
Files with VIM modelines could call some unsafe VIM functions
(CVE-2007-2438).

Modelines are disabled in the default config (/etc/vimrc) of
openSUSE.

The problem affected only openSUSE 10.2 and fixed packages were
released for it.

- kdebase3 flash-player interaction problem
A problem with the interaction between the Flash Player and the
Konqueror web browser was fixed. The problem could lead to key presses
leaking to the applet instead of the browser. (CVE-2007-2022)

Additionaly khc_indexbuilder restricts the commands that can be
executed with EGID 'man' now.

This update has been released for SUSE Linux Desktop 1.0, SUSE Linux
Enterprise Server 9, Novell Linux Desktop 9 and SUSE Linux 9.3,10.0,
10.1 and openSUSE 10.2.

SUSE Linux Enterprise 10 will receive the fixes together with the
Service Pack 1.

- mod_perl insufficient quoting of special characters
Insufficient quoting of special characters in the PATH_INFO variable
could lead to excessive resource consumption and a denial of
service via a specially crafted URL. (CVE-2007-1349)

This problem only affects the Apache 1 version of mod_perl and so
only affects SUSE Linux Enterprise Server 8 and 9, which received
updates.

2) Pending Vulnerabilities, Solutions, and Work-Arounds

- Kernel Update

We are currently preparing a kernel update for SUSE Linux Enterprise Server 9,
Novell Linux Desktop 9, SUSE Linux 10.0 and 10.2 to roll out fixes for
current security problems. It is scheduled to be be released in the week of
June 11.

3) Authenticity Verification and Additional Information

- Announcement authenticity verification:

SUSE security announcements are published via mailing lists and on Web
sites. The authenticity and integrity of a SUSE security announcement is
guaranteed by a cryptographic signature in each announcement. All SUSE
security announcements are published with a valid signature.

To verify the signature of the announcement, save it as text into a file
and run the command

gpg --verify <file>

replacing <file> with the name of the file containing the announcement.
The output for a valid signature looks like:

gpg: Signature made <DATE> using RSA key ID 3D25D3D9
gpg: Good signature from "SuSE Security Team <security@suse.de>"

where <DATE> is replaced by the date the document was signed.

If the security team's key is not contained in your key ring, you can
import it from the first installation CD. To import the key, use the
command

gpg --import gpg-pubkey-3d25d3d9-36e12d04.asc

- Package authenticity verification:

SUSE update packages are available on many mirror FTP servers all over the
world. While this service is considered valuable and important to the free
and open source software community, the authenticity and integrity of a
package needs to be verified to ensure that it has not been tampered with.

The internal 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, replacing <file.rpm> with the
filename of the RPM package downloaded. The package is unmodified if it
contains a valid signature from build@suse.de with the key ID 9C800ACA.

This key is automatically imported into the RPM database (on RPMv4-based
distributions) and the gpg key ring of 'root' during installation. You can
also find it on the first installation CD and included at the end of this
announcement.

- SUSE runs two security mailing lists to which any interested party may
subscribe:

opensuse-security@opensuse.org
- General Linux and SUSE security discussion.
All SUSE security announcements are sent to this list.
To subscribe, send an e-mail to
<opensuse-security+subscribe@opensuse.org>.

- SUSE's announce-only mailing list.
Only SUSE's security announcements are sent to this list.
To subscribe, send an e-mail to
<suse-security-announce-subscribe@suse.com>.
