YES.  wu-ftpd will call compress with the file name as an argument if you
request the file name ending in .Z. You have to be able to write out a file
name containing the shell code to exploit the bug. 

The problem is that the file have to be 1100 chars long , with the shellcode 
within. But wu-ftpd doesn`t allow/handle so long filenames. 

I mentioned the compress bug back in 1998 and again in 2000, it finally 
got fixed on some of the  newer SuSE releases (not sure about Red Hat, 
I dont use it).

Compress in Red Hat 7.1 and 7.2 isnt fixed to this bug.
