This signature detects attempts to exploit a known vulnerability against Linux kernel while processing a certain type of SCTP packet. A successful attack can result in a denial-of-service condition.
The sctp_association_free function in net/sctp/associola.c in the Linux kernel before 3.15.2 does not properly manage a certain backlog value, which allows remote attackers to cause a denial of service (socket outage) via a crafted SCTP packet.
