"Mariusz Mlynski and others discovered several flaws in Firefox that
allowed a remote attacker to conduct cross-site scripting (XSS)
attacks. (CVE-2012-4194, CVE-2012-4195)

Antoine Delignat-Lavaud discovered a flaw in the way Firefox handled
the Location object. If a user were tricked into opening a specially
crafted page, a remote attacker could exploit this to bypass security
protections and perform cross-origin reading of the Location object.
(CVE-2012-4196).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
