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.

- kismet remote buffer overflow
This update fixes two buffer overflow bugs in kismet that could
probably be exploited to execute commands remotely.

This issue affects SUSE Linux 9.0 up to 9.3 and is tracked by the Mitre
CVE IDs CAN-2005-2626 and CAN-2005-2627.

- openvpn denial of service attack
A denial of service problem was fixed in openvpn:
With disabled TLS authentication a malicious client could close
OpenVPN connections of other clients.

This is tracked by the Mitre CVE ID CAN-2005-2531 and affects SUSE Linux
9.0 up to 9.2.

- gaim AOL bugfix
This update fixes a problem with an earlier GAIM security update which
broke the AIM protocol.

The bug affected SUSE Linux 9.0, 9.1 and 9.2.

- ldap TLS forwarding problem
A security update was released for openldap2 and pam_ldap.
This update adds a missing feature to the TLS support. Previously it was
possible that a password was sent in clear text over the network even with
TLS support when the connection was redirected to a slave LDAP server.

This issue is tracked by the Mitre CVE ID CAN-2005-2069.

All SUSE Linux products were affected by this issue.

- kaudiocreator cddb file overwrite problem
A bug in kaudiocreator was fixed which allows to overwrite files
with the privileges of the user running kaudiocreator by placing
'/../../' in the title of a CDDB entry (used by default).

No Mitre CVE Entry up to now.


2) Pending Vulnerabilities, Solutions, and Work-Arounds

- evolution format string problems
Format string problems were reported in the evolution mail client.

We are preparing updates for this issue.

- Mozilla "Host:" overflow problem

A buffer overflow in the IDN handling was announced for Mozilla based
browsers.

We are preparing updates for this issue.

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.
