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 Mac OS X systems, this issue is addressed with Security Update 2011-002. 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.
