3. Problem description:

RealPlayer is a media player that provides media playback locally and
via streaming. It plays RealAudio, RealVideo, MP3, 3GPP Video, Flash, SMIL
2.0, JPEG, GIF, PNG, RealPix, RealText, and more.

A buffer overflow bug was found in the way RealPlayer processes SMIL files.
An attacker could create a specially crafted SMIL file that could combine
with a malicious Web server to execute arbitrary code when the file was
opened by a user. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2005-1766 to this issue.

All users of RealPlayer are advised to upgrade to this updated package,
which contains RealPlayer version 10.0.5 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.

This update is available via Red Hat Network.  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.
