CVE-2014-5077

Published: 1 August 2014

The sctp_assoc_update function in net/sctp/associola.c in the Linux kernel through 3.15.8, when SCTP authentication is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by starting to establish an association between two endpoints immediately after an exchange of INIT and INIT ACK chunks to establish an earlier association between these endpoints in the opposite direction.

From the Ubuntu Security Team

Jason Gunthorpe reported a flaw with SCTP authentication in the Linux kernel. A remote attacker could exploit this flaw to cause a denial of service (NULL pointer dereference and OOPS).
