Descriptions

The bnep_sock_ioctl function in net/bluetooth/bnep/sock.c in the Linux kernel before 2.6.39 does not ensure that a certain device field ends with a '\0' character, which allows local users to obtain potentially sensitive information from kernel stack memory, or cause a denial of service (BUG and system crash), via a BNEPCONNADD command.

La función de bnep_sock_ioctl en net/bluetooth/bnep/sock.c en versiones del kernel de Linux anteriores a v2.6.39 no garantiza que un campo de dispositivo determinado termine con un '\0', lo que permite a usuarios locales obtener información sensible de la pila del kernel, o causar una denegación de servicio (por caída del sistema), a través de un comando BNEPCONNADD.
