CVE-2006-2274 SCTP DATA fragments DoS
Last modified: 2007-11-30 17:07:24 EST
Linux SCTP before 2.6.17 allows remote attackers to cause a denial of service
via a packet that contains two or more DATA fragments, which causes an skb
pointer to refer back to itself when the full message is reassembled, leading to
infinite recursion in the sctp_skb_pull function.
This issue hasn't been reproduced with RHEL4, but the vulnerable code is the
same as upstream.
The upstream fix can be found here:
committed in stream U4 build 36.1. A test kernel with this patch is available
