Topic

Updated firefox packages that fix various security issues are now available
for Red Hat Enterprise Linux 5.

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

[Updated 16th July 2008]
The nspluginwrapper package has been added to this advisory to satisfy a
missing package dependency issue.

Description

Mozilla Firefox is an open source Web browser.

An integer overflow flaw was found in the way Firefox displayed certain web
content. A malicious web site could cause Firefox to crash, or execute
arbitrary code with the permissions of the user running Firefox.
(CVE-2008-2785)

A flaw was found in the way Firefox handled certain command line URLs. If
another application passed Firefox a malformed URL, it could result in
Firefox executing local malicious content with chrome privileges.
(CVE-2008-2933)

All firefox users should upgrade to these updated packages, which contain
Firefox 3.0.1 that corrects these issues.
