"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-2013-0788)

A flaw was found in the way Same Origin Wrappers were implemented in
Firefox. A malicious site could use this flaw to bypass the
same-origin policy and execute arbitrary code with the privileges of
the user running Firefox. (CVE-2013-0795)

A flaw was found in the embedded WebGL library in Firefox. A web page
containing malicious content could cause Firefox to crash or,
potentially, execute arbitrary code with the privileges of the user
running Firefox. Note: This issue only affected systems using the
Intel Mesa graphics drivers. (CVE-2013-0796)

An out-of-bounds write flaw was found in the embedded Cairo library in
Firefox. 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-2013-0800)

A flaw was found in the way Firefox handled the JavaScript history
functions. A malicious site could cause a web page to be displayed
that has a baseURI pointing to a different site, allowing cross-site
scripting (XSS) and phishing attacks. (CVE-2013-0793)

Red Hat would like to thank the Mozilla project for reporting these
issues. Upstream acknowledges Olli Pettay, Jesse Ruderman, Boris
Zbarsky, Christian Holler, Milan Sreckovic, Joe Drew, Cody Crews,
miaubiz, Abhishek Arya, and Mariusz Mlynski as the original reporters
of these issues.

For technical details regarding these flaws, refer to the Mozilla
security advisories for Firefox 17.0.5 ESR. You can find a link to the
Mozilla advisories in the References section of this erratum.

All Firefox users should upgrade to these updated packages, which
contain Firefox version 17.0.5 ESR, which corrects these issues. After
installing the update, Firefox must be restarted for the changes to
take effect."
