Description

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)
