Version Summary:Apple has released a security advisory and updated software to address the Fraudulent TURKTRUST Inc. digital certificates.
 

Description
 
Third-party certificate registrar TURKTRUST Inc. issued fraudulent certificates for *.google.com through incorrectly created subsidiary certificate registrars. Because the third-party registrar is trusted by the Microsoft Trusted Root Certification Authorities Store, Windows-based systems may be vulnerable to spoofing attacks. If an attacker possessed the fraudulent certificate, the attacker could masquerade as a valid google.com host, allowing the attacker to conduct man-in-the-middle attacks or phishing attacks, potentially leading to information disclosure.

Reports indicate that attacks using the fraudulent certificates have occurred in the wild.

Microsoft has released a security advisory and software updates to revoke the certificate on affected Windows systems.

Microsoft has released a security advisory at the following link: 2798897

Microsoft customers can obtain updates directly by using the links in the security advisory. These updates are also distributed by Windows automatic update features and available on the Microsoft Update service. Microsoft Windows Server Update Services (WSUS), Systems Management Server, and System Center Configuration Manager can assist administrators in deploying software updates.

Apple has released security advisory at the following link: HT5642. Apple has released updated software at the following link: iOS 6.1 Software Update.

Mozilla has released a security bulletin at the following link: MFSA 2013-20. Mozilla has released updated versions at the following links:
