NVD evaluator notes for CVE-2010-2075

Comment: Per: http://www.unrealircd.com/txt/unrealsecadvisory.20100612.txt 'Official precompiled Windows binaries (SSL and non-ssl) are NOT affected. CVS is also not affected. 3.2.8 and any earlier versions are not affected. Any Unreal3.2.8.1.tar.gz downloaded BEFORE November 10 2009 should be safe, but you should really double-check, see next.'
