Description

Mozilla Firefox, Mozilla Thunderbird, and Mozilla SeaMonkey contain a user-after-free error when handling child nodes. The issue is due to the 'AttributeChildRemoved()' method when removing child nodes from the 'nsDOMAttribute' node. This may allow a remote attacker to dereference already freed memory and potentially execute arbitrary code.
