kernel brute segfault

[FEEB]

I am running RHEL4 on Quad Opteron hardware.

I started to see these in the logs:

kernel: brute[29385]: segfault at 0000000000000000 rip 0000000008048e33 rsp
00000000ffffca30 error 4

What is brute? What can I do about this?

Thanks

Just for the record. Brute is an executable that is part of some SSH
cracking package. The package tries to SSH to a predefined B-block of
addresses using predefined combinations of login names and passwords (for
instance login "test" with password "test").
It generates a log file with combinations that returned a shell.

The package was installed via a compromised user account (user has been
known to distribute his passwords) from Romania and placed in /var/tmp and
therefore invisible to "locate" (in RedHat several directories are exempt
from updatedb, one of them is /var/tmp).

The user has been dealt with.
