Details

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)
