Descriptions

Multiple integer overflows in the (1) pppol2tp_sendmsg function in net/l2tp/l2tp_ppp.c, and the (2) l2tp_ip_sendmsg function in net/l2tp/l2tp_ip.c, in the PPPoL2TP and IPoL2TP implementations in the Linux kernel before 2.6.36.2 allow local users to cause a denial of service (heap memory corruption and panic) or possibly gain privileges via a crafted sendto call.

Múltiples desbordamientos de entero en las funciones (1) pppol2tp_sendmsg de net/l2tp/l2tp_ppp.c, y (2) l2tp_ip_sendmsg de net/l2tp/l2tp_ip.c, en las implementaciones PPPoL2TP y IPoL2TP en el kernel de Linux anterior a v2.6.36.2, permiten a usuarios locales provocar una denegación de servicio (corrupción en el montón de la memoria y pánico) o puede que aumentar privilegios a través de una llamada sendto.
