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)

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-2014-1493, CVE-2014-1510, CVE-2014-1511,
CVE-2014-1512, CVE-2014-1513, CVE-2014-1514)

Several information disclosure flaws were found in the way Firefox
processed malformed web content. An attacker could use these flaws to
gain access to sensitive information such as cross-domain content or
protected memory addresses or, potentially, cause Firefox to crash.
(CVE-2014-1497, CVE-2014-1508, CVE-2014-1505)

A memory corruption flaw was found in the way Firefox rendered certain
PDF files. An attacker able to trick a user into installing a
malicious extension could use this flaw to crash Firefox or,
potentially, execute arbitrary code with the privileges of the user
running Firefox. (CVE-2014-1509)

Red Hat would like to thank the Mozilla project for reporting these
issues. Upstream acknowledges Benoit Jacob, Olli Pettay, Jan Varga,
Jan de Mooij, Jesse Ruderman, Dan Gohman, Christoph Diehl, Atte
Kettunen, Tyson Smith, Jesse Schwartzentruber, John Thomson, Robert
O'Callahan, Mariusz Mlynski, Jüri Aedla, George Hotz, and the
security research firm VUPEN as the original reporters of these
issues.

For technical details regarding these flaws, refer to the Mozilla
security advisories for Firefox 24.4.0 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 24.4.0 ESR, which corrects these issues. After
installing the update, Firefox must be restarted for the changes to
take effect.
