CVE-2011-2999  (opens in a new tab)
CWE-79  (opens in a new tab)

How to fix?

Upgrade RHEL:6 firefox to version 0:3.6.23-2.el6_1 or higher.
This issue was patched in RHSA-2011:1341.

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 3.6.23 and 4.x through 5, Thunderbird before 6.0, and SeaMonkey before 2.3 do not properly handle "location" as the name of a frame, which allows remote attackers to bypass the Same Origin Policy via a crafted web site, a different vulnerability than CVE-2010-0170.
