SUSE Security Summary Report

Announcement ID: SUSE-SR:2006:018
Date: Fri, 28 Jul 2006 16:00:00 +0000
Cross-References: CVE-2006-3082

Content of this advisory:
1) Solved Security Vulnerabilities:
- gpg2 denial of service attack
2) Pending Vulnerabilities, Solutions, and Work-Arounds:
- Mozilla Firefox / Thunderbird / Suite Security Update
3) Authenticity Verification and Additional Information

______________________________________________________________________________

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.

- gpg2 denial of service attack

It is possible to crash (denial of service) the GNU Privacy Guard
(gpg) by supplying a specifically crafted message specifying a
very large UID, which leads to an out of memory situation or an
integer overflow.

gpg itself has been updated some weeks ago already, gpg2 (the 1.9.x
version) was updated this week.

This issue is tracked by the Mitre CVE ID CVE-2006-3082.

2) Pending Vulnerabilities, Solutions, and Work-Arounds

- Mozilla Firefox / Thunderbird / Suite Security Update

We will be updating Mozilla in the next days.

- Mozilla Firefox:

All Mozilla Firefox on released distributions will be upgraded
to version 1.5.0.5.
This update affects: Novell Linux Desktop 9, SUSE Linux Enterprise 10,
SUSE Linux 9.2 - 10.1

The update might break manually installed Firefox Extensions.

- Mozilla Thunderbird

Mozilla Thunderbird on released distributions will be upgraded
to version 1.5.0.5.

- Mozilla Suite discontinuation / replacement by Seamonkey.

Since the Mozilla Suite is no longer maintained, we will most
likely replace it by Seamonkey 1.0.3.

This update affects: SUSE Linux Desktop 1, SUSE Linux Enterprise
Server 8, SUSE Linux Enterprise Server 9, Novell Linux Desktop 9,
SUSE Linux 9.2 - 10.0.

This will likely also require updates of evolution, beagle,
and other dependent packages, so it might take some time.

In general we recommend not using the Mozilla Suite any longer.

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 lt;filegt;

replacing lt;filegt; with the name of the file containing the announcement.
The output for a valid signature looks like:

gpg: Signature made lt;DATEgt; using RSA key ID 3D25D3D9
gpg: Good signature from "SuSE Security Team lt;security@suse.degt;"

where lt;DATEgt; 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 lt;file.rpmgt;

to verify the signature of the package, replacing lt;file.rpmgt; 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.
