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-2014-1574, CVE-2014-1578, CVE-2014-1581, CVE-2014-1576,
CVE-2014-1577)

A flaw was found in the Alarm API, which allows applications to schedule
actions to be run in the future. A malicious web application could use this
flaw to bypass cross-origin restrictions. (CVE-2014-1583)

Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Bobby Holley, Christian Holler, David Bolter, Byron
Campen Jon Coppeard, Atte Kettunen, Holger Fuhrmannek, Abhishek Arya,
regenrecht, and Boris Zbarsky as the original reporters of these issues.

For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 31.2.0 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 31.2.0 ESR, which corrects these issues. After installing
the update, Firefox must be restarted for the changes to take effect.
