Summary

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.
