Descriptions

Integer underflow in the dccp_parse_options function (net/dccp/options.c) in the Linux kernel before 2.6.33.14 allows remote attackers to cause a denial of service via a Datagram Congestion Control Protocol (DCCP) packet with an invalid feature options length, which triggers a buffer over-read.

Desbordamiento de entero en la función dccp_parse_options (net/DCCP/options.c) en el kernel de Linux antes de la versión v2.6.33.14 permite a atacantes remotos causar una denegación de servicio a través de un paquete de datagramas del Protocolo de control de congestión (DCCP) con una longitud de opciones de características no válida, lo que provoca una sobre lectura de un búfer.
