______________________________________________________________________________

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.

- tiff buffer overflow in helpers
A stack-based buffer overflow in tiffsplit was fixed that can be
triggered with long filenames (CVE-2006-2656).

An additional buffer overflow was fixed in tiff2pdf (CVE-2006-2193).

All SUSE Linux based products are affected.

Both tools are not setuid but may be exploited in conjunction with
other applications (as helper tools).

Exploitation of those two problems is unlikely.

- snort URL parsing evasion

An evasion attack on URL parsing in the intrusion detection
system snort was fixed. The faulty code is in the http_inspect
preprocessor.

All SUSE Linux based products containing snort are affected and
the issue is tracked by the Mitre CVE ID CVE-2006-2769.

- xine-lib buffer overflow in HTTP plugin
Missing length checks in the HTTP plugin of XINE could lead to a
buffer overflow on the heap when accessing remote video streams.

All SUSE Linux versions are affected and the issue is tracked by
the Mitre CVE ID CVE-2006-2802.

2) Pending Vulnerabilities, Solutions, and Work-Arounds

- Configuration of Maintenance Information Mails

This concerns our Enterprise customers only.

If you miss the Maintenance Information Mails we send for every
patch after migration to the Novell Portal, please visit the page
below to configure your mail settings for these maintenance mails.

http://support.novell.com/suseNotifications/index.jsp

This page allows selection of Mails per registered SUSE Linux
Enterprise product.

- php4 problems with last update

The last security update for PHP 4 broke functionality of some
applications in array handling.

This is tracked in https://bugzilla.novell.com/show_bug.cgi?id=185516

We are currently testing fixed packages for this problem and hope
to release them tomorrow.

- Adobe Reader security problems
Adobe Reader 7.0.8 was released fixing security problems.

We are working on updated packages.

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.
