Description Marcel Holtmann 2006-05-09 18:37:58 UTC

Linux SCTP before 2.6.17 allows remote attackers to cause a denial of service
via incoming IP fragmented COOKIE_ECHO and HEARTBEAT SCTP control chunks.

This issue hasn't been reproduced with RHEL4, but the vulnerable code is the
same as upstream.

The upstream fix can be found here:
