______________________________________________________________________________

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.

- OpenPBS potential security problems

An audit of OpenPBS found some potential security vulnerabilities that
may allow the compromising of a system remotely and/or locally. An update was
released to fix these issues.

This affects SUSE Linux 9.2 up to 10.1.


- mailman several security problems

The mailing list manager mailman was updated to fix the following
security issues:

- A malicious user could visit a specially crafted URI and inject an
apparent log message into Mailman's error log which might induce an
unsuspecting administrator to visit a phishing site. This has been
blocked. Thanks to Moritz Naumann for its discovery. CVE-2006-4624.

- Fixed denial of service attack which can be caused by some
standards-breaking RFC 2231 formatted headers. CVE-2006-2941.

- Several cross-site scripting issues have been fixed. Thanks
to Moritz Naumann for their discovery. CVE-2006-3636

- Fixed an un exploitable format string vulnerability. Discovery
and fix by Karl Chen. Analysis of non-exploit-ability by Martin
'Joey' Schulze. Also thanks go to Lionel Elie
Mamane. CVE-2006-2191.

This affects all our current products containing mailman.


- python overflow in repr()

A buffer overflow within python's repr() function has been fixed.
The CVE number CVE-2006-4980 has been assigned to this issue.

This affects SUSE Linux 9.2,9.3,10.0 and 10.1, SUSE Linux Enterprise Server
9, and SUSE Linux Enterprise 10.


- libmusicbrainz overflows

The libmusicbrainz library has been updated to fix various buffer
overflows that could by exploited by malicious servers to execute
arbitrary code.

This update affects SUSE Linux 9.2, 9.3, 10.0 and 10.1, SUSE Linux
Enterprise Desktop 10, SUSE Linux Enterprise Server 9, and Novell
Linux Desktop 9.

It is tracked by the Mitre CVE ID CVE-2006-4197.

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.
