Red Hat, Inc. Red Hat Security Advisory
Synopsis: Updated gaim client fixes Jabber plug-in vulnerability
Advisory ID: RHSA-2002:098-14

CVE Names: CAN-2002-0384
---------------------------------------------------------------------
1. Topic:
Updated gaim packages are now available for Red Hat Linux 7.1, 7.2, and
7.3. These updates fix a buffer overflow in the Jabber plug-in module.
2. Relevant releases/architectures:
Red Hat Linux 7.1 - alpha, i386, ia64
Red Hat Linux 7.2 - i386, ia64
Red Hat Linux 7.3 - i386
3. Problem description:
Gaim is an instant messaging client based on the published TOC protocol
from AOL. Versions of gaim prior to 0.58 contain a buffer overflow in the
Jabber plug-in module.
Users of gaim should update to these errata packages containing gaim
0.59 which is not vulnerable to this issue.
Please note that gaim version 0.57 had an additional security problem
which has been fixed in version 0.58 (CAN-2002-0377), however Red Hat
Linux did not ship with version 0.57 and was not vulnerable to this
issue.
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.
