Apparently upgrading to 2.0.11-pr1 fixes the problem:
http://www.frsirt.com/english/advisories/2007/1364
So, if your friend is indeed wanting to fix his/her version it seems like this would work.
What I understand from looking at it is that the bug allows the attacker to split the HTTP header, in other words, create another one. If there exists an intermediary (e.g. cache proxy server), then this allows the attacker to 'poison' the cache proxy server. This allows for stealing information from an innocent victim, or providing them with a custom malicious page.
Sounds tricky/difficult to exploit.
I found an interesting explanation of the attack:
