Actually, it is quite irrelevant, if the user is confined, because the 
exploit can be modified to disable selinux, giving full access to the 
system. Fact is, this exploit is quite nasty in that respect, as you can 
pretty much modify anything.
So, in other words, it just makes the attackers life a tiny bit harder, 
unless she is a script kiddie.
