Note:

Certificates Trust Policy

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. Safari relies on the certificate store of the host operating system to determine if an SSL server certificate is trustworthy. For Mac OS X systems, this issue is addressed with Security Update 2011-002. For iOS, this issue is addressed with iOS 4.3.2 and iOS 4.2.7. For Windows systems, applying the update described in Microsoft Knowledge Base Article 2524375 will cause Safari to regard these certificates as untrusted.
