Does it actually bypass a protection that exec-shield claims to give, or is it doing something that exec-shield doesn't claim to be able to stop? There's no love lost between the pax and exec-shield crews: http://marc.theaimsgroup.com/?l=linux-kernel&m=107209069402935&w=2 http://marc.theaimsgroup.com/?l=linux-kernel&m=107209256604442&w=2 So I'd evaluate very carefully any claim made by either crew. It's possible that there is a real hole in exec-shield. It's also possible that the "exploit" is simply doing stuff that exec-shield won't stop by design - remember that a design *goal* of exec-shield was to not be as kernel-intrusive as pax, so it would have a smaller footprint and be less likely to break stuff unintentionally.
