Descriptions

Use-after-free vulnerability in Mozilla Firefox before 3.6.26 and 4.x through 9.0, Thunderbird before 3.1.18 and 5.0 through 9.0, and SeaMonkey before 2.7 might allow remote attackers to execute arbitrary code via vectors related to incorrect AttributeChildRemoved notifications that affect access to removed nsDOMAttribute child nodes.

Una vulnerabilidad de uso después de liberaciónen Mozilla Firefox antes de v3.6.26 y v4.x hasta la v9.0, Thunderbird antes de v3.1.18 y v5.0 hasta la v9.0 y SeaMonkey antes de v2.7 podría permitir a atacantes remotos ejecutar código de su elección a través de vectores relacionados con notificaciones AttributeChildRemoved incorrectas que afectan el acceso a nodos hijos nsDOMAttribute.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Mozilla Firefox. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the way Firefox handles nsDOMAttribute child removal. It is possible to remove a child without setting the removed child pointer to NULL, thus leaving it still accessible as a dangling pointer. Subsequent use of this pointer allows for remote code execution.
