| Hi.
|
| I don't know if this one is known, but I can't recall seeing anything
| about it. If it is old news I apologize.
|
| I discovered a bug in the inetd that comes with NetKit-B-0-08 and older.
|
| If a single SYN is sent to port 13 of the server, inetd will die of Broken
| Pipe:
If you send a SYN to *any* internally maintained inetd service and
immediately follow it up with a RST, inetd will DIE upon receiving
the next connection request. See Phrack 49 (my last venture into
DOS attacks) for a brief synopsis and code...
