libsecurity
CVE-ID: CVE-2009-2409
Available for: Mac OS X v10.5.8, Mac OS X Server v10.5.8, Mac OS X v10.6 and v10.6.1, Mac OS X Server v10.6 and v10.6.1
Impact: Support for X.509 certificates with MD2 hashes may expose users to spoofing and information disclosure as attacks improve
Description: There are known cryptographic weaknesses in the MD2 hash algorithm. Further research could allow the creation of X.509 certificates with attacker controlled values that are trusted by the system. This could expose X.509 based protocols to spoofing, man in the middle attacks, and information disclosure. While it is not yet considered computationally feasible to mount an attack using these weaknesses, this update disables support for an X.509 certificate with an MD2 hash for any use other than as trusted root certificate. This is a proactive change to protect users in advance of improved attacks against the MD2 hash algorithm.
