Topic

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.

Description

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 terminate
unexpectedly or, potentially, execute arbitrary code with the privileges of
the user running Firefox. (CVE-2013-5609, CVE-2013-5616, CVE-2013-5618,
CVE-2013-6671, CVE-2013-5613)

A flaw was found in the way Firefox rendered web content with missing
character encoding information. An attacker could use this flaw to possibly
bypass same-origin inheritance and perform cross-site scripting (XSS)
attacks. (CVE-2013-5612)

It was found that certain malicious web content could bypass restrictions
applied by sandboxed iframes. An attacker could combine this flaw with
other vulnerabilities to execute arbitrary code with the privileges of the
user running Firefox. (CVE-2013-5614)

Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Ben Turner, Bobby Holley, Jesse Ruderman, Christian
Holler, Masato Kinugawa, Daniel Veditz, Jesse Schwartzentruber, Nils, Tyson
Smith, and Atte Kettunen as the original reporters of these issues.

For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 24.2.0 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 24.2.0 ESR, which corrects these issues. After installing
the update, Firefox must be restarted for the changes to take effect.
