potentially execute code with the privileges of the user invoking Firefox.
(CVE-2013-0801, CVE-2013-1669)

Cody Crews discovered that some constructors could be used to bypass
restrictions enforced by their Chrome Object Wrapper (COW). An attacker
could exploit this to conduct cross-site scripting (XSS) attacks.
(CVE-2013-1670)

It was discovered that the file input element could expose the full local

A use-after-free was discovered when resizing video content whilst it is
playing. An attacker could potentially exploit this to execute code with
the privileges of the user invoking Firefox. (CVE-2013-1674)

without being properly initialized, which could lead to information
leakage. (CVE-2013-1675)

Abhishek Arya discovered multiple memory safety issues in Firefox. If
the user were tricked into opening a specially crafted page, an attacker
could possibly exploit these to cause a denial of service via application
crash, or potentially execute code with the privileges of the user
invoking Firefox. (CVE-2013-1676, CVE-2013-1677, CVE-2013-1678,
CVE-2013-1679, CVE-2013-1680, CVE-2013-1681)
