CWE-94  (opens in a new tab)

How to fix?

Upgrade RHEL:6 firefox to version 0:3.6.20-2.el6_1 or higher.
This issue was patched in RHSA-2011:1164.

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 3.6.20, SeaMonkey 2.x, Thunderbird 3.x before 3.1.12, and possibly other products does not properly handle the dropping of a tab element, which allows remote attackers to execute arbitrary JavaScript code with chrome privileges by establishing a content area and registering for drop events.
