Vulnerability Details : CVE-2004-2761

The MD5 Message-Digest Algorithm is not collision resistant, which makes it easier for context-dependent attackers to conduct spoofing attacks, as demonstrated by attacks on the use of MD5 in the signature algorithm of an X.509 certificate.

Microsoft Advisory http://www.microsoft.com/technet/security/advisory/961509.mspx Microsoft Security Advisory (961509): Research proves feasibility of collision attacks against MD5 - 12/30/2008 Revision Note: Advisory published Advisory Summary:Microsoft is aware that research was published at a security conference proving a successful attack against X.509 digital certificates signed using the MD5 hashing algorithm. This attack method would allow an attacker to generate additional digital certificates with different content that have the same digital signature as an original certificate. The MD5 algorithm had previously shown a vulnerability, but a practical attack had not yet been demonstrated.Release Date:2008-12-30
