Descriptions

The do_tcp_setsockopt function in net/ipv4/tcp.c in the Linux kernel before 2.6.37-rc2 does not properly restrict TCP_MAXSEG (aka MSS) values, which allows local users to cause a denial of service (OOPS) via a setsockopt call that specifies a small value, leading to a divide-by-zero error or incorrect use of a signed integer.

La función do_tcp_setsockopt de net/ipv4/tcp.c en el kernel de Linux anterior a 2.6.37-rc2 no restringe adecuadamente los valores TCP_MAXSEG (también conocidos como MSS), esto permite a usuarios locales provocar una denegación de servicio (OOPS) mediante una llamada setsockopt que especifica un valor pequeño, lo que conduce a un error de división entre cero o un uso incorrecto de un entero asignado.
