perl suid exploit

[Michael Mansour <micoots yahoo com>]

Hi,

I run perl 5.8.3 in suid mode on Fedora Core 1, and
have recently detected an attempted exploit which
basically crashed my system (well, I was able to
recover by removing the 15 byte /etc/ld.so.preload
file which tries to reference, as part of the exploit,
a /tmp/getuid.so file).

I've brought the server up again, but am not sure now
how I can defend against this attack since FC1 and
perl 5.8.3 are the latest.

Anyone have any suggestions?

Thanks.

Michael.
