Details

An updated RealPlayer package that fixes a buffer overflow issue is now
available.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

[Updated 05 Jul 2005]
The previous package for Red Hat Enterprise Linux 4 did not contain the
proper fix for this issue. This erratum has been updated with a replacement
package that corrects this issue

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.
