Last night I applied the OpenSSH patch from July 29, 2003 and rebooted
the server. Now, whenever I run the cat command, I receive a
"Segmentation Fault" error. Here is the output of strace:

I am unsure how to proceed here. My thinking is that the OpenSSH update
altered a library needed by cat. Has anyone else encountered this issue
or has any suggestions on how to proceeed fixing this error? I have yet
to find another binary on the system having the same errors.
