Descriptions

The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST extension implementations in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 do not check whether a certain length value is sufficiently large, which allows local users to cause a denial of service (integer underflow and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr and __skb_get_nlattr_nest functions before the vulnerability was announced.

Las implementaciones de extensión (1) BPF_S_ANC_NLATTR y (2) BPF_S_ANC_NLATTR_NEST en la función sk_run_filter en net/core/filter.c en el kernel de Linux hasta 3.14.3 no comprueban si un valor de cierta longitud es lo suficientemente grande, lo que permite a usuarios locales causar una denegación de servicio (subdesbordamiento de enteros y caída de sistema) a través de instrucciones BPF manipuladas. NOTA: el código afectado fue trasladado a las funciones __skb_get_nlattr y __skb_get_nlattr_nest antes de anunciar la vulnerabilidad.
