Descriptions
The BPF_S_ANC_NLATTR_NEST extension implementation in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 uses the reverse order in a certain subtraction, which allows local users to cause a denial of service (over-read and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr_nest function before the vulnerability was announced.
La implementación de extensión 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 utiliza el orden inverso en cierta resta, lo que permite a usuarios locales causar una denegación de servicio (sobrelectura y caída de sistema) a través de instrucciones BPF manipuladas. NOTA: el código afectado fue trasladado a la función __skb_get_nlattr_nest antes de anunciar la vulnerabilidad.
