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 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.
- MozillaThunderbird 188.8.131.52
MozillaThunderbird was updated to version 184.108.40.206, fixing various bugs including 1 security bug:
Thunderbird was released for SUSE Linux 10.1, openSUSE 10.2 and 10.3.
- mozilla-xulrunner181 security release
The Mozilla render engine mozilla-xulrunner181 was updated to version 220.127.116.11, fixing various bugs including 1 security bug:
It was released for openSUSE 10.2 and 10.3.
- tkimg GIF problems
Two vulnerabilities while parsing GIF images were fixed in tkimg. (CVE-2008-0553, CVE-2006-4484)
tkimg was updated for openSUSE 10.2 and 10.3.
- cups png and pdf problems
Two minor security problems were fixed in the print server CUPS:
- specially crafted PNG files could cause an integer overflow in the png filter (CVE-2008-1693).
- specially crafted pdf files with embedded fonts could crash pdftops (CVE-2008-1693).
Updates were released for all products.
- qemu raw disk format emulation escape
Local attackers in a QEMU guest session could use raw formatted disk images to access the hosting environment. (CVE-2008-2004)
Updates were released for SUSE Linux 10.1, openSUSE 10.2 and 10.3.
- gstreamer010-plugins-good speex problem
gstreamer-plugins-good was also affected by the speex problem, where specially crafted files or streams could potentially be abused to trick applications that support speex into executing arbitrary code (CVE-2008-1686).
gstreamer010-plugins-good was updated on all distributions containing this package.
- pan nzb file denial of service
In the PAN newsreader specially crafted nzb files could trigger a heap based buffer overflow that could potentially be exploited to execute arbitrary code (CVE-2008-2363).
pan was only affected on openSUSE 10.3 and was updated there.
- libxslt match processing overflow
A libxslt XSL-match processing head overflow has been fixed, which could be used to potentially execute code if an attacker would be able to inject XSL matches. (CVE-2008-1767)
All SUSE Linux products received 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 email@example.com"
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 firstname.lastname@example.org 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:
email@example.com - General Linux and SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an e-mail to firstname.lastname@example.org.
email@example.com - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an e-mail to firstname.lastname@example.org.
