Synopsis: Updated Gaim packages fix security vulnerabilities Advisory ID: RHSA-2004:045-01 Issue date: 2004-02-09 Updated on: 2004-02-09 Product: Red Hat Enterprise Linux Keywords: gaim im Cross references: Obsoletes: CVE Names: CAN-2004-0006 CAN-2004-0008 - ---------------------------------------------------------------------

1. Topic:

Updated Gaim packages that fix a pair of security vulnerabilities are now available.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386

3. Problem description:

Gaim is an instant messenger client that can handle multiple protocols.

Stefan Esser audited the Gaim source code and found a number of bugs that have security implications. Many of these bugs do not affect the version of Gaim distributed with version 2.1 of Red Hat Enterprise Linux.

A buffer overflow exists in the HTTP Proxy connect code. If Gaim is configured to use an HTTP proxy for connecting to a server, a malicious HTTP proxy could run arbitrary code as the user running Gaim. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0006 to this issue.

An integer overflow in Gaim 0.74 and earlier, when allocating memory for a directIM packet for AIM/Oscar, results in heap overflow. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0008 to this issue.

Users of Gaim should upgrade to these erratum packages, which contain a backported security patch correcting this issue.

Red Hat would like to thank Steffan Esser for finding and reporting these issues and Jacques A. Vidrine for providing initial patches.

4. Solution:

Before applying this update, make sure all previously released errata relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs.

Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.

If up2date fails to connect to Red Hat Network due to SSL Certificate Errors, you need to install a version of the up2date client with an updated certificate. The latest version of up2date is available from the Red Hat FTP site and may also be downloaded directly from the RHN website:

https://rhn.redhat.com/help/latest-up2date.pxt
