Descriptions

The SCTP implementation in the Linux kernel through 3.17.2 allows remote attackers to cause a denial of service (system crash) via a malformed ASCONF chunk, related to net/sctp/sm_make_chunk.c and net/sctp/sm_statefuns.c.

La implementación SCTP en el kernel de Linux hasta 3.17.2 permite a atacantes remotos causar una denegación de servicio (caída del sistema) a través de un chunk ASCONF malformado, relacionado con net/sctp/sm_make_chunk.c y net/sctp/sm_statefuns.c.

A flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled malformed Address Configuration Change Chunks (ASCONF). A remote attacker could use either of these flaws to crash the system.
