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-2012-4214, CVE-2012-4215, CVE-2012-4216, CVE-2012-5829,

could cause Firefox to crash or, possibly, execute arbitrary code with the
privileges of the user running Firefox. (CVE-2012-4202)

HTML and CSS content with chrome privileges. (CVE-2012-4210)

A flaw was found in the way Firefox decoded the HZ-GB-2312 character
encoding. A web page containing malicious content could cause Firefox to
run JavaScript code with the permissions of a different website.

Malicious content could possibly use this flaw to allow restricted content
to be loaded by plug-ins. (CVE-2012-4209)

Malicious content could use this flaw to perform cross-site scripting
attacks. (CVE-2012-5841)
