1) problem description, brief discussion, solution, upgrade information

Gaim is a multi-protocol instant-messaging client. Stefan Esser found 12 vulnerabilities in gaim that can lead to a remote system compromise with the privileges of the user running GAIM. The GAIM package that SUSE LINUX ships is affected by just two of these bug: - Yahoo Packet Parser Overflow - HTTP Proxy Connect Overflow

The first vulnerability is easy to exploit and results in a classic stack overflow which can be used to execute arbitrary code. The latter vulnerability requires the gaim client use a HTTP proxy under the control of the attacker. The exploitation of this bug results in arbitrary code execution too.

There is no known workaround.

Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, to apply the update use the command "rpm -Fhv file.rpm". Our maintenance customers are being notified individually. The packages are being offered to install from the maintenance web.

2) Pending vulnerabilities in SUSE Distributions and Workarounds:

- kernel binaries for SLES8 AMD64 Due to a human failure the kernel binaries of SuSE Linux Enterprise Server 8 for AMD64 lack the fix described in SuSE-SA:2004:003. The kernel-source packages and the packages for IA64 are *not* affected. New packages are available at our maintenance-web.

- mc By using a special combination of links in archive files it is possible to execute arbitrary commands while mc tries to open it in its VFS. New packages are available on our FTP servers.

- mod_gzip (apache-contrib) The apache module mod_gzip is vulnerable to remote code execution while running in debug-mode. We do not ship this module in debug-mode but future versions will include the fix. Additionally the mod_gzip code was audited to fix more possibly security related bugs. After more testing a new apache-contrib RPM package will be released.

- tripwire Tripwire is a file integrity checker. The version of tripwire included with SuSE Linux 9.0 crashs when a requested file does not exists. New packages are available on our FTP servers.

- XDM (XFree86, xf86) A missing check for failure conditions in the PAM code of XDM can lead to local root access in conjunction with Kerberos or other authentication methods. New packages are available on our FTP servers.

- 3ddiag Some 3ddiag scripts handle temporary files in an insecure manner. Thanks to Stefan Nordhausen for reporting some of these issues. New packages are available on our FTP servers.

- mod_auth_shadow (apache-contrib) This apache module ignores account expiration dates. The update will be released together with mod_gzip.

- cvsup cvsup uses a library path which is world-writeable. This behavior can lead to local privilege escalation. Thanks to Matthias Andree for notifying us. Upcoming SuSE Linux versions have an automatic check enabled to detect these types of bugs. New packages are available on our FTP servers.

- nmap Due to a bad interaction between kernel and user-space for pre- calculated IP checksums nmap did not work on SUSE LINUX 9.0. New packages are available on our FTP servers.

- netpbm Some tools in the netpbm suite create files in an insecure manner that
