Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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 terminate
unexpectedly or, potentially, execute arbitrary code with the
privileges of the user running Firefox. (CVE-2013-5590, CVE-2013-5597,
CVE-2013-5599, CVE-2013-5600, CVE-2013-5601, CVE-2013-5602)

It was found that the Firefox JavaScript engine incorrectly allocated
memory for certain functions. An attacker could combine this flaw with
other vulnerabilities to execute arbitrary code with the privileges of
the user running Firefox. (CVE-2013-5595)

A flaw was found in the way Firefox handled certain Extensible
Stylesheet Language Transformations (XSLT) files. An attacker could
combine this flaw with other vulnerabilities to execute arbitrary code
with the privileges of the user running Firefox. (CVE-2013-5604)

Red Hat would like to thank the Mozilla project for reporting these
issues. Upstream acknowledges Jesse Ruderman, Christoph Diehl, Dan
Gohman, Byoungyoung Lee, Nils, and Abhishek Arya as the original
reporters of these issues.

For technical details regarding these flaws, refer to the Mozilla
security advisories for Firefox 17.0.10 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 17.0.10 ESR, which corrects these issues.
After installing the update, Firefox must be restarted for the changes
to take effect.
