3. Problem description:

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

A buffer overflow bug was found in the way RealPlayer processes RAM files.
An attacker could create a specially crafted RAM file which could execute
arbitrary code when opened by a user. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2005-0755 to
this issue.

All users of RealPlayer are advised to upgrade to this updated package,
which contains RealPlayer version 10.0.4 and is not vulnerable to this
issue.
