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.

Hmm.. What about splitting the shellcode into different directories and the 
requesting the full path to the file (directories and all) ending in .Z?
