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-2013-1682, CVE-2013-1684, CVE-2013-1685, CVE-2013-1686,
CVE-2013-1687, CVE-2013-1690)

It was found that Firefox allowed data to be sent in the body of
XMLHttpRequest (XHR) HEAD requests. In some cases this could allow
attackers to conduct Cross-Site Request Forgery (CSRF) attacks.

Timing differences in the way Firefox processed SVG image files could
allow an attacker to read data across domains, potentially leading to
information disclosure. (CVE-2013-1693)

Two flaws were found in the way Firefox implemented some of its internal
structures (called wrappers). An attacker could use these flaws to bypass
some restrictions placed on them. This could lead to unexpected behavior or
a potentially exploitable crash. (CVE-2013-1694, CVE-2013-1697)

Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Gary Kwong, Jesse Ruderman, Andrew McCreight,
Abhishek Arya, Mariusz Mlynski, Nils, Johnathan Kuskos, Paul Stone, Boris
Zbarsky, and moz_bug_r_a4 as the original reporters of these issues.

For technical details regarding these flaws, refer to the Mozilla
security advisories for Firefox 17.0.7 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 17.0.7 ESR, which corrects these issues. After installing
the update, Firefox must be restarted for the changes to take effect.
