This was first posted to the FreeBSD security list on the 9th of August, subsequently discussed on freebsd-stable and freebsd-hackers... no one seems to care, even though it is able to lock up 2.2.6, 2.2.8, and 3.2.x machines consistantly. I have also been told that it affects NetBSD and OpenBSD, though I haven't confirmed it.
Standard resource drain DoS..
Someone with the know-how care to fix?
man login.conf login.conf on *BSDs can be used to set resource limits for users, CPUtime, memory locked etc etc... I removed my limits on a user and was able to overload my machine (BSDI 4.0), after putting my limits back on there is no problem.. Anyone that is not using a login.conf or other type of resource restriction is asking for punishment.. More of a 'bug' in the setup / configuration of the system on the admin's part, not on the OS if you ask me.. my $.02 deposited.. cheers, -- jason
