Content of this advisory:
1) Solved Security Vulnerabilities:
- kaffeine buffer overflow

______________________________________________________________________________

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.

- kaffeine buffer overflow

The media player kaffeine contains a heap overflow in the handling
of streaming HTTP URLs, which potentially allows remote attackers
to cause a denial of service attack or to execute code by supplying
a very long URL.

This issue is tracked by the Mitre CVE ID CVE-2006-0051.

SUSE Linux 9.2 up to 10.0 are affected by this problem.

- mailman denial of service attack

The component for handling attachments in the mailing list manager
Mailman suffered from a DoS in cases where a multipart message was
malformed. This update makes Mailman more robust.

This issue is tracked by the Mitre CVE ID CVE-2006-0052.

SUSE Linux 9.1 up to 9.3 and SUSE Linux Enterprise Server 9 are
affected.

- xzgv heap overflow

A heap overflow was fixed in the viewer xzgv which could be exploited
by viewing a JPEG picture within the CMYK/YCCK color space.

Additionally, this update fixes --exif-orient not working due to
some improper patch for compilation with GCC 4 on SUSE Linux 10.0.

This issue is tracked by the Mitre CVE ID CVE-2006-1060 and affects
SUSE Linux 9.1 up to 10.0.

2) Pending Vulnerabilities, Solutions, and Work-Arounds

- clamav security problems
Clamav has a new version (0.88.1) that fixes among other things the following
security problems:

- An integer overflow in the PE header parser (CVE-2006-1630).

- Format string bugs in the logging code could potentially be
exploited to execute arbitrary code (CVE-2006-1630).

- Access to invalid memory could lead to a crash (CVE-2006-1630).

Updates are currently being tested, but due to a regression on the
IA64 platform will likely be available on Monday.

- SUSE Portal will be shutdown soon
This item affects only our enterprise customers.

The old SUSE portal (portal.suse.com) has been migrated to the
Novell support pages at http://support.novell.com/.

The old portal will be finally shut down in some weeks, but latest
at end of April.

If you still use the old SUSE portal, please migrate your account
to the Novell portal as soon as possible.

The http://portal.suse.com/ page contains a link to the account
migration page.

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.
