CVE-2014-3688

Published: 24 October 2014

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.

From the Ubuntu Security Team

It was discovered that excessive queuing by SCTP (Stream Control Transmission Protocol) implementation in the Linux kernel can cause memory pressure. A remote attacker could exploit this flaw to cause a denial of service.
