*Launch Services

Available for: Mac OS X v10.6 and v10.6.1, Mac OS X Server v10.6 and v10.6.1

Impact: Attempting to open unsafe downloaded content may not lead to a warning

Description: When Launch Services is called to open a quarantined folder, it will recursively clear quarantine information from all files contained within the folder. The quarantine information that is cleared is used trigger a user warning prior to opening the item. This would allow the user to launch a potentially unsafe item, such as an application, without being presented with the appropriate warning dialog. This update addresses the issue by not clearing this quarantine information from the folder's content. This issue does not affect systems prior to Mac OS X v10.6. Credit: Apple.

*libsecurity

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. Credit to Dan Kaminsky of IOACTIVE and Microsoft Vulnerability Research (MSVR) for reporting this issue.
