Descriptions
The add_del_listener function in kernel/taskstats.c in the Linux kernel 2.6.39.1 and earlier does not prevent multiple registrations of exit handlers, which allows local users to cause a denial of service (memory and CPU consumption), and bypass the OOM Killer, via a crafted application.
La función add_del_listener situada en kernel/taskstats.c del kernel de Linux v2.6.39.1 y versiones anteriores, no impide múltiples registros de los controladores de salida, que permiten a usuarios locales provocar una denegación de servicio (consumo de memoria y CPU), y eludir el OOM Killer, a través de una aplicación modificada.
