Hi Greg, > ULE (Unidirectional Lightweight Encapsulation RFC 4326) decapsulation > code has a bug that allows an attacker to send a malformed ULE packet > with SNDU length of 0 and bring down the receiving machine. This patch > fix the bug and has been tested on version 2.6.17.11. This bug is 100% > reproducible and the modified source code (GPL) used to produce this bug > will be posted on http://nrg.cs.usm.my/downloads.htm shortly. The > kernel will produce a dump during CRC32 checking on faulty ULE packet. the upstream code changed for 2.6.18. It has a different way of addressing this issue, but it also changes a lot of other stuff in the whole code. However it might be worth looking at it, because the upstream code might be still vulnerable.
