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_process_unk_param function in net/sctp/sm_make_chunk.c in the Linux kernel 2.6.33.3 and earlier, when SCTP is enabled, allows remote attackers to cause a denial of service (system crash) via an SCTPChunkInit packet containing multiple invalid parameters that require a large amount of error data.
