3. Problem description:

Mozilla Thunderbird is a standalone mail and newsgroup client.

A buffer overflow bug was found in the way Thunderbird processes GIF
images. It is possible for an attacker to create a specially crafted GIF
image, which when viewed by a victim will execute arbitrary code as the
victim. The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CAN-2005-0399 to this issue.

A bug was found in the Thunderbird string handling functions. If a
malicious website is able to exhaust a system's memory, it becomes possible
to execute arbitrary code. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2005-0255 to this issue.

Users of Thunderbird are advised to upgrade to this updated package which
contains Thunderbird version 1.0.2 and is not vulnerable to these issues.
