USN-3188-1 advisory.

    Andrey Konovalov discovered that the SCTP implementation in the Linux kernel improperly handled validation
    of incoming data. A remote attacker could use this to cause a denial of service (system crash).

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
