Microsoft Fixed Serious Spoofing Vulnerability in the Secure Sockets Layer (SSL)

Microsoft has updated its operating systems to fix a potentially serious spoofing vulnerability in the secure sockets layer (SSL) protocol. TLS and SSL encrypt the segments of network connections at the Application Layer to ensure secure end-to-end transit at the Transport Layer.

Microsoft Released Security Patch for SSL

Microsoft on Tuesday August 10, 2010, released MS10-049 to fix the bug in Windows Server 2008, Windows 7 and 12 other versions of Windows that are still under support. The patch updates a part of the operating system known Secure Channel (SChannel), which is responsible for implementing SSL/TLS (transport layer security).

According to TheRegister, Microsoft’s update follows the revision in January of RFC 5246, the request-for-comments document that previously mapped out the technical specifications for the protocol. The new controlling blueprint for SSL/TLS communications is RFC 5746. Since then, other packages, including OpenSSL, RedHat Linux and Oracle’s Java, have also been patched.

Microsoft rated the severity of the vulnerability as “important,” the second-highest classification on its four-tier scale. The bulletin correctly said the SSL vulnerability could be exploited only in concert with another attack – such as ARP spoofing or DNS cache poisoning – that allowed someone to perform a man-in-the-middle attack.
