1. Topic:

New micq packages are available which fix a buffer overflow vulnerability.

2. Relevant releases/architectures:

Red Hat Powertools 6.0 - alpha, i386, sparc

Red Hat Powertools 6.1 - alpha, i386, sparc

Red Hat Powertools 6.2 - alpha, i386, sparc

Red Hat Powertools 7.0 - alpha, i386

3. Problem description:

A buffer overflow exists in the micq package, which allows arbitrary
commands to be executed. This update fixes the problem.

4. Solution:

To update all RPMs for your particular architecture, run:

rpm -Fvh 

where  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 directly *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.
