3. Problem description:

RealPlayer is a media player that provides media playback locally and
via streaming.

A format string bug was discovered in the way RealPlayer processes RealPix
(.rp) files. It is possible for a malformed RealPix file to execute
arbitrary code as the user running RealPlayer. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name CAN-2005-2710
to this issue.

All users of RealPlayer are advised to upgrade to this updated package,
which contains RealPlayer version 10.0.6 and 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.
