1. Topic:
Updated gaim packages are now available for Red Hat Powertools 7.
These updates fix a vulnerability in the URL handler.
2. Relevant releases/architectures:
Red Hat Powertools 7.0 - alpha, i386
3. Problem description:
Gaim is an all-in-one instant messaging client that lets you use a number of
messaging protocols such as AIM, ICQ, and Yahoo, all at once.
Versions of gaim prior to 0.59.1 contain a bug in the URL handler of
the manual browser option. A link can be carefully crafted to contain
an arbitrary shell script which will be executed if the user clicks on
the link.
Users of gaim should update to these errata packages containing gaim
0.59.1 which is 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.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
