Hmm - we fixed a dodgy traceroute flaw for RH7.0. So RH7.0 is safe. However it now turns out that this dodgy flaw is in fact exploitable. Bugtraq reference: http://www.securityfocus.com/archive/1/137778 To be honest, a rebuild of the RH7.0 SRPM is a quick and easy fix :-) For original RH7.0 bug see bug #13466
