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 <[email protected]> wrote: From: netinfinity <[email protected]> Subject: Re: [Full-disclosure] New Source Code Vulnerability Scanner (Free 30 Day Trial) To: [email protected] Date: Saturday, December 4, 2010, 11:53 AM 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.
