CVE-2014-4667

Published: 3 July 2014

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.

From the Ubuntu Security Team

An integer underflow flaw was discovered in the Linux kernel's handling of the backlog value for certain SCTP packets. A remote attacker could exploit this flaw to cause a denial of service (socket outage) via a crafted SCTP packet.
