Synopsis :

The remote Mac OS X host contains a web browser that is affected by
multiple vulnerabilities.

Description :

The installed version of Firefox is earlier than 10.0.5 and thus, is
potentially affected by the following security issues :

- An error exists in the ASN.1 decoder when handling zero
length items that can lead to application crashes.
(CVE-2012-0441)

- Multiple memory corruption errors exist. (CVE-2012-1937,
CVE-2012-1939)

- Two heap-based buffer overflows and one heap-based use-
after-free error exist and are potentially exploitable.
(CVE-2012-1940, CVE-2012-1941, CVE-2012-1947)

- The inline-script blocking feature of the 'Content
Security Policy' (CSP) does not properly block inline
event handlers. This error allows remote attackers to
more easily carry out cross-site scripting attacks.
(CVE-2012-1944)

- A use-after-free error exists related to replacing or
inserting a node into a web document. (CVE-2012-1946)
