Re: Local DoS in FreeBSD

This was first posted to the FreeBSD security list on the 9th of August,
subsequently discussed on freebsd-stable and freebsd-hackers... no one
seems to care, even though it is able to lock up 2.2.6, 2.2.8, and 3.2.x
machines consistantly. I have also been told that it affects NetBSD and
OpenBSD, though I haven't confirmed it.

Someone with the know-how care to fix?

Fixing this has been discussed internally, I imagine, by many of the
affected OS's.  The problem is a resource stavation issue - in this
case mbuf's.  Arguably, it shouldn't "lock up", just freeze up anything
that does networking.

I imagine you could lock up more than just the *BSD's with this program.
