CVE-2012-1956  (opens in a new tab)
CWE-79  (opens in a new tab)

How to fix?

Upgrade RHEL:6 firefox to version 0:10.0.8-1.el6_3 or higher.
This issue was patched in RHSA-2012:1350.

NVD Description

Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

Mozilla Firefox before 15.0, Thunderbird before 15.0, and SeaMonkey before 2.12 do not prevent use of the Object.defineProperty method to shadow the location object (aka window.location), which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via vectors involving a plugin.
