Security Advisory Description

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.

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.
Impact
Remote attackers may be able to cause a denial-of-service (DoS) using malformed or duplicate ASCONF chunk.
