CVE-2011-1573

Published: 6 October 2011

net/sctp/sm_make_chunk.c in the Linux kernel before 2.6.34, when addip_enable and auth_enable are used, does not consider the amount of zero padding during calculation of chunk lengths for (1) INIT and (2) INIT ACK chunks, which allows remote attackers to cause a denial of service (OOPS) via crafted packet data.

From the Ubuntu Security Team

It was discovered that the Stream Control Transmission Protocol (SCTP) implementation incorrectly calculated lengths. If the net.sctp.addip_enable variable was turned on, a remote attacker could send specially crafted traffic to crash the system.
