Descriptions

The sctp_sf_ootb function in net/sctp/sm_statefuns.c in the Linux kernel before 4.8.8 lacks chunk-length checking for the first chunk, which allows remote attackers to cause a denial of service (out-of-bounds slab access) or possibly have unspecified other impact via crafted SCTP data.

La función sctp_sf_ootb en net/sctp/sm_statefuns.c en el kernel Linux en versiones anteriores a 4.8.8 carece de comprobación de longitud de fragmento para el primer fragmento, lo que permite a atacantes remotos provocar una denegación de servicio (acceso slab fuera de límites) o tener otro posible impacto no especificado a través de datos SCTP manipulados.

A flaw was found in the Linux kernel's implementation of the SCTP protocol. A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash.
