Key facts

Description

The SCTP implementation in the Linux kernel before 3.17.4 allows remote attackers to cause a denial of service (memory consumption) by triggering a large number of chunks in an association's output queue, as demonstrated by ASCONF probes, related to net/sctp/inqueue.c and net/sctp/sm_statefuns.c.
