Discovered by Irwan Amir Widjaja <[EMAIL PROTECTED]> and Daniel Roethlisberger <[EMAIL PROTECTED]>. Two popular encryption plugins for Back Orifice 2000 have been found to have serious security flaws: BO_CAST and BO2K IDEA. Both have been fixed. The flaw is that due to a small error in one line of the MD5 hash algorithm code, any password generated the same hash. The fixed versions are available at: IDEA: http://www.wynne.demon.co.uk/maw/IDEAEncrypt.zip BO_CAST: http://www.roe.ch/cgi-bin/bo_cast.pl More information is available at: http://www.securityfocus.com/level2/?go=vulnerabilities&id=561 http://www.securityfocus.com/level2/?go=vulnerabilities&id=562 Ben Greenbaum SecurityFocus www.securityfocus.com
