I was thinking about another way to possible bypass this code. POC: grep -fruit will trick the system into thinking it is a fruit thus crashing because of stackoverflow and juice overflow. On Sat, Dec 4, 2010 at 12:32 PM, Georgi Guninski <guninski () guninski com>wrote:

Let me fire up my vulnerability research whitepaper generator. /mzimplementation issues aside, are the theoretic foundations of the scanner correct? some points. 1. analyzing the grep(1) codebase. what if grep has anti-scanning backdoor - like a compiler backdoor? 2. the scanner reproducibly reports backdoors in /dev/urandom - it is even not an .EXE! -- joro _______________________________________________ Full-Disclosure - We believe in it.
