Description Eugene Teo (Security Response) 2008-07-29 08:20:45 UTC 
+++ This bug was initially created as a clone of Bug #457013 +++

Description of problem:
The length field in the PPPOE header wasn't checked completely. It lacks of a
lower-bound check. Also, call skb_copy_datagram_iovec instead of memcpy_toiovec
so that paged packets (rare for PPPOE) are handled properly.
