Hi, I've seen a bunch of scans for this exploit across my hosts, and have already heard of some hosts compromised by it: http://seclists.org/fulldisclosure/2014/Apr/240 So if you run Nagios NRPE, please make sure to: - Firewall it off appropriately - Use its config options for restricting who can talk to it - Disable client specification of command arguments if possible - Upgrade to a fixed version Cheers, Andy -- http://bitfolk.com/ -- No-nonsense VPS hosting
