page containing malicious content could cause Firefox to crash or,
potentially, execute arbitrary code with the privileges of the user running
Firefox. (CVE-2013-0744, CVE-2013-0746, CVE-2013-0750, CVE-2013-0753,
CVE-2013-0754, CVE-2013-0762, CVE-2013-0766, CVE-2013-0767, CVE-2013-0769)

A flaw was found in the way Chrome Object Wrappers were implemented.
Malicious content could be used to cause Firefox to execute arbitrary code
via plug-ins installed in Firefox. (CVE-2013-0758)

A flaw in the way Firefox displayed URL values in the address bar could
allow a malicious site or user to perform a phishing attack.
(CVE-2013-0759)

An information disclosure flaw was found in the way certain JavaScript
functions were implemented in Firefox. An attacker could use this flaw to
bypass Address Space Layout Randomization (ASLR) and other security
