Subject: Sharutils buggy?

Well you could check out some e-mail programs etc... Imagine that an 
attacker sends e-mail to root@...e.host with a uuencoded attachment. The 
attacker has local access to the machine and knows that root's e-mail 
program calls system("uudecode %s",file) would allow the attacker to 
setup the uuencode file in such a fashion as to make this work... 
whether such a case exists is pure speculation. But out of boredom I've 
attached a theorhetical exploit.

peace,
core
