## Description

The SSL provider component in Microsoft Windows Vista SP2, Windows Server 2008 SP2, R2, and R2 SP1, Windows 7 Gold and SP1, Windows 8, Windows Server 2012, and Windows RT does not properly handle encrypted packets, which allows man-in-the-middle attackers to conduct SSLv2 downgrade attacks against (1) SSLv3 sessions or (2) TLS sessions by intercepting handshakes and injecting content, aka "Microsoft SSL Version 3 and TLS Protocol Security Feature Bypass Vulnerability."
