Description Marcel Holtmann 2006-05-09 14:37:22 EDT

The ECNE chunk handling in Linux SCTP before 2.6.17 allows remote attackers to
cause a denial of service via an unexpected chunk when the session is in CLOSED
state.

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

The upstream fix can be found here:

Comment 5 Jason Baron 2006-05-22 15:07:56 EDT

committed in stream U4 build 36.1. A test kernel with this patch is available
