Descriptions

The vold volume manager daemon on Android 3.0 and 2.x before 2.3.4 trusts messages that are received from a PF_NETLINK socket, which allows local users to execute arbitrary code and gain root privileges via a negative index that bypasses a maximum-only signed integer check in the DirectVolume::handlePartitionAdded method, which triggers memory corruption, as demonstrated by Gingerbreak.

El demonio de vold volume manager en Android versión 3.0 y versiones 2.x anterior a 2.3.4, confía en los mensajes que son recibidos desde un socket PF_NETLINK, que permite a los usuarios locales ejecutar código arbitrario y alcanzar privilegios de root por medio de un índice negativo que omite la comprobación de un entero firmado maximum-only en el método DirectVolume::handlePartitionAdded, que activa una corrupción de memoria, como es demostrado por Gingerbreak.
