Updated firefox packages that fix several security issues are now available
for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having critical
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

Mozilla Firefox is an open source web browser. XULRunner provides the XUL
Runtime environment for Mozilla Firefox.

Several flaws were found in the processing of malformed web content. A web
page containing malicious content could cause Firefox to crash or,
potentially, execute arbitrary code with the privileges of the user running
Firefox. (CVE-2013-0744, CVE-2013-0746, CVE-2013-0750, CVE-2013-0753,
CVE-2013-0754, CVE-2013-0762, CVE-2013-0766, CVE-2013-0767, CVE-2013-0769)

A flaw was found in the way Chrome Object Wrappers were implemented.
Malicious content could be used to cause Firefox to execute arbitrary code
via plug-ins installed in Firefox. (CVE-2013-0758)

A flaw in the way Firefox displayed URL values in the address bar could
allow a malicious site or user to perform a phishing attack.

An information disclosure flaw was found in the way certain JavaScript
functions were implemented in Firefox. An attacker could use this flaw to
bypass Address Space Layout Randomization (ASLR) and other security
restrictions. (CVE-2013-0748)

For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 10.0.12 ESR. You can find a link to the Mozilla
advisories in the References section of this erratum.

Red Hat would like to thank the Mozilla project for reporting these issues.

Firefox version 10.0.12 ESR, which corrects these issues. After installing
the update, Firefox must be restarted for the changes to take effect.
