Descriptions

The sctp_assoc_lookup_asconf_ack function in net/sctp/associola.c in the SCTP implementation in the Linux kernel through 3.17.2 allows remote attackers to cause a denial of service (panic) via duplicate ASCONF chunks that trigger an incorrect uncork within the side-effect interpreter.

La función sctp_assoc_lookup_asconf_ack en net/sctp/associola.c en la implementación SCTP en el kernel de Linux hasta 3.17.2 permite a atacantes remotos causar una denegación de servicio (kernel panic) a través de trozos ASCONF duplicados que provocan una liberación incorrecta dentro del intérprete de efectos secundarios.

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