CVE-2011-2378  (opens in a new tab)
CWE-94  (opens in a new tab)

How to fix?

Upgrade Centos:6 firefox to version 0:3.6.20-2.el6_1 or higher.

NVD Description

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

The appendChild function in Mozilla Firefox before 3.6.20, Thunderbird 3.x before 3.1.12, SeaMonkey 2.x, and possibly other products does not properly handle DOM objects, which allows remote attackers to execute arbitrary code via unspecified vectors that lead to dereferencing of a "dangling pointer."
