APPLE-SA-2011-04-14-4 Security Update 2011-002

Security Update 2011-002 is now available and addresses the
following:

Certificate Trust Policy
Available for:  Mac OS X v10.5.8, Mac OS X Server v10.5.8,
Mac OS X v10.6.7, Mac OS X Server v10.6.7
Impact:  An attacker with a privileged network position may intercept
user credentials or other sensitive information
Description:  Several fraudulent SSL certificates were issued by a
Comodo affiliate registration authority. This may allow a man-in-the-
middle attacker to redirect connections and intercept user
credentials or other sensitive information. This issue is addressed
by blacklisting the fraudulent certificates.
Note: For iOS, this issue is addressed with iOS 4.3.2 and iOS 4.2.7.
For Windows systems, Safari relies on the certificate store of the
host operating system to determine if an SSL server certificate is
trustworthy. Applying the update described in Microsoft Knowledge
Base Article 2524375 will cause Safari to regard these certificates
as untrusted. The article is available at
http://support.microsoft.com/kb/2524375
