catdoc-0.90 is full of buffer overruns. The cloest things to a remote exploit
is a reported exploit document, of which I have not got a copy of to try. It
would is quite believable, given the level of buffer overruns, This could be a
security problem if catdoc is used with privilege users do not have for
automated indexing purposes or otherwise used with raised privilege.

There are lots of overruns for bad guys to exploit. I think the attached patch
fixes all of the bugs. The author has been sent this patch over a week ago and
received to response. (Even if nobody can think of an exploit situation having
buffer overruns is not cool).
