CVE-2008-4576

Published: 15 October 2008

sctp in Linux kernel before 2.6.25.18 allows remote attackers to cause a denial of service (OOPS) via an INIT-ACK that states the peer does not support AUTH, which causes the sctp_process_init function to clean up active transports and triggers the OOPS when the T1-Init timer expires.

From the Ubuntu security team

It was discovered that the SCTP stack did not correctly handle INIT-ACK. A remote user could exploit this by sending specially crafted SCTP traffic which would trigger a crash in the system, leading to a denial of service. This issue did not affect Ubuntu 8.10.
