Descriptions

Mozilla Firefox 3.0.7 on Windows 7 allows remote attackers to execute arbitrary code via unknown vectors related to the _moveToEdgeShift XUL tree method, which triggers garbage collection on objects that are still in use, as demonstrated by Nils during a PWN2OWN competition at CanSecWest 2009.

Mozilla Firefox versión 3.0.7 en Windows 7, permite a los atacantes remotos ejecutar código arbitrario por medio de vectores desconocidos relacionados con el método de árbol _moveToEdgeShift XUL, que desencadena un garbage collection en objetos que todavía están en uso, como es demostrado por Nils durante la competición PWN2OWN en CanSecWest 2009.

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.
The specific flaw exists in the XUL tree method _moveToEdgeShift(). In some cases this call will trigger garbage collection routines on in use objects which will result in a future call to a dangling pointer. This can be leveraged to execute arbitrary code under the context of the current user.
