CVE-2008-4618

The Stream Control Transmission Protocol (sctp) implementation in the Linux kernel before 2.6.27 does not properly handle a protocol violation in which a parameter has an invalid length, which allows attackers to cause a denial of service (panic) via unspecified vectors, related to sctp_sf_violation_paramlen, sctp_sf_abort_violation, sctp_make_abort_violation, and incorrect data types in function calls.

From the Ubuntu Security Team

It was discovered that the SCTP stack did not correctly handle bad packet lengths. 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.
