Descriptions

The sock_setsockopt function in net/core/sock.c in the Linux kernel before 3.5 mishandles negative values of sk_sndbuf and sk_rcvbuf, which allows local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUF or (2) SO_RCVBUF option.

La función sock_setsockopt en net/core/sock.c en el kernel de Linux en versiones anteriores a 3.5 no maneja adecuadamente valores negativos de sk_sndbuf y sk_rcvbuf, lo que permite a usuarios locales provocar una denegación de servicio (corrupción de memoria y caída del sistema) o posiblemente tener otro impacto no especificado aprovechando la capacidad CAP_NET_ADMIN para una llamada al sistema setsockopt manipulada con la opción (1) SO_SNDBUF o (2) SO_RCVBUF.
