"An updated firefox package that fixes one security issue is now
available for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having
critical security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

Mozilla Firefox is an open source web browser.

A heap-based buffer overflow flaw was found in the way Firefox handled
PNG (Portable Network Graphics) images. A web page containing a
malicious PNG image could cause Firefox to crash or, possibly, execute
arbitrary code with the privileges of the user running Firefox.
(CVE-2011-3026)

All Firefox users should upgrade to this updated package, which
corrects this issue. After installing the update, Firefox must be
restarted for the changes to take effect."
