you will want to upgrade to 2.2.19 when its available since 2.2.18 and below have another security hole (actually two). the first being a race condition that allows suid executables to be ptraced, this is potentially allows for root compromise. the other allows users to read arbitrary memory through a bug in sysctl() (depending on the attackers luck they could potentially grab a password or other sensitive information). both are only locally exploitable. (i know of no exploit for the ptrace race at this time, there is a proof of concept exploit for the sysctl() bug). -- Ethan Benson http://www.alaska.net/~erbenson/
