CVE-2010-3705

Published: 1 October 2010

The sctp_auth_asoc_get_hmac function in net/sctp/auth.c in the Linux kernel before 2.6.36 does not properly validate the hmac_ids array of an SCTP peer, which allows remote attackers to cause a denial of service (memory corruption and panic) via a crafted value in the last element of this array.

From the Ubuntu Security Team

Dan Rosenberg discovered that SCTP did not correctly handle HMAC calculations. A remote attacker could send specially crafted traffic that would crash the system, leading to a denial of service.
