This is sunkill.c It Affects at least solaris 2.5.1 machines, both sun4c and sun4m achitecutures. I imagine it affects all solaris 2.5.1 machines, both sparc and x86, but im not sure. It basically works by opening a telnet connection on the victim machine and sends a few bad telnet negotiation options, then flooods the port with lots of ^D characters. This uses all the streams memory (i think) on the victims machine and causes the kernel to get very angry. The machien crawls to a halt, the cursor in X stops moving, the machine is unresponsive to the network. Its a bad situation all around.
In testing against Linux 2.0.29, it appears to cause the load average to slowly rise. It has been running for a couple of minutes, and the host seems to be tolerating it OK, but it does seem a little annoyed. Nothing like what you report vs. Solaris. The Linux box shows no signs of terminating the connection, though - IMHO, that is a bad thing. How long does it have to run vs. Solaris to cause mayhem? Has anyone else found any other OS's vulnerable?
