At least the freeware version of Softwin's anti-virus solution BitDefender Free Edition ships with a completely outdated zlib 1.1.3 that is vulnerable to CA-2007-07 . The zlib.dll included in the versions 7.2, 8.0 and the current 10.0 of their products is dated 1998-07-12 and shows the version 1.1.3. Stefan Kanthak
