"It was discovered that the browser engine used in Firefox contained a
memory corruption flaw. If a user were tricked into opening a
specially crafted web page, a remote attacker could cause Firefox to
crash or potentially execute arbitrary code as the user invoking the
program. (CVE-2012-4191)

It was discovered that Firefox allowed improper access to the Location
object. An attacker could exploit this to obtain sensitive
information. (CVE-2012-4192).

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."
