Descriptions

Schannel in Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 does not properly restrict Diffie-Hellman Ephemeral (DHE) key lengths, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via unspecified vectors, aka "Schannel Information Disclosure Vulnerability."

Schannel en Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 y R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold y R2, y Windows RT Gold y 8.1 no restringe correctamente las longitudes de las claves Diffie-Hellman Ephemeral (DFE), lo que facilita a atacantes remotos vencer los mecanismos de protección criptográficos a través de vectores no especificados, también conocido como 'vulnerabilidad de la divulgación de información de Schannel.'
