Summary
Red Hat Security Advisory: mozilla security update

Notes

Topic
Updated mozilla packages that fix a buffer overflow issue are now available. This update has been rated as having critical security impact by the Red Hat Security Response Team.
Details
Mozilla is an open source Web browser, advanced email and newsgroup client, IRC chat client, and HTML editor. A bug was found in the Mozilla 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. Please note that other security issues have been found that affect Mozilla. These other issues have a lower severity, and are therefore planned to be released as additional security updates in the future. Users of Mozilla should upgrade to these updated packages, which contain a backported patch and are not vulnerable to these issues.
