Synopsis
The remote Windows host is affected by a security feature bypass vulnerability.Description
The remote Windows host is affected by a security feature bypass vulnerability, known as FREAK (Factoring attack on RSA-EXPORT Keys), due to the support of weak EXPORT_RSA cipher suites with keys less than or equal to 512 bits. A man-in-the-middle attacker may be able to downgrade the SSL/TLS connection to use EXPORT_RSA cipher suites which can be factored in a short amount of time, allowing the attacker to intercept and decrypt the traffic.Solution
Microsoft has released a set of patches for Windows 2003, Vista, 2008, 7, 2008 R2, 8, 2012, 8.1, and 2012 R2.See Also
