Synopsis :

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

Description :

Updated firefox packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 5, 6, and 7.

Red Hat Product Security 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-2015-2708, CVE-2015-0797, CVE-2015-2710,
CVE-2015-2713)

A heap-based buffer overflow flaw was found in the way Firefox
processed compressed XML data. An attacker could create specially
crafted compressed XML content that, when processed by Firefox, could
cause it to crash or execute arbitrary code with the privileges of the
user running Firefox. (CVE-2015-2716)

Red Hat would like to thank the Mozilla project for reporting these
issues. Upstream acknowledges Jesse Ruderman, Mats Palmgren, Byron
Campen, Steve Fink, Aki Helin, Atte Kettunen, Scott Bell, and Ucha
Gobejishvili as the original reporters of these issues.

All Firefox users should upgrade to these updated packages, which
contain Firefox version 38.0 ESR, which corrects these issues. After
installing the update, Firefox must be restarted for the changes to
take effect.
