Don't forget you can add a pipe to filter the pulp. grep -fruit | grep -v pulp -v will omit pulp, and various regexes and additives can fortify with calcium or vitamin C. --- On Sat, 12/4/10, netinfinity <netinfinity.securitylab () gmail com> wrote: From: netinfinity <netinfinity.securitylab () gmail com> Subject: Re: [Full-disclosure] New Source Code Vulnerability Scanner (Free 30 Day Trial) To: full-disclosure () lists grok org uk Date: Saturday, December 4, 2010, 11:53 AM I was thinking about another way to possible bypass this code. POC: grep -fruitĀ will trick the system into thinking it is a fruit thus crashing because of stackoverflow and juice overflow.

This code has two very obvious detection bypass vulnerabilities:
1) It fails to scan dotfiles in the starting directory,
2) It can be tricked into not producing any output by creating a file
named "-q" in the starting dir.
Let me fire up my vulnerability research whitepaper generator.

implementation 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.
