Descriptions

Double free vulnerability in Microsoft Outlook 2007 SP3 and 2010 SP1 and SP2 allows remote attackers to execute arbitrary code by including many nested S/MIME certificates in an e-mail message, aka "Message Certificate Vulnerability."

Vulnerabilidad de doble liberación en Microsoft Outlook 2007 (SP3) y 2010 (SP1 y SP2) permite a atacantes remotos ejecutar código a discrección incluyendo varios certificados S/MIME anidados en un mensaje de correo electrónico, tambien conocido como "Vulnerabilidad de Certificado de Mensaje".

A design bug in X.509 certificate chain validation (RFC 3280) allows attackers to trigger (blind) HTTP requests for both external as well as internal IPs if a specially-crafted, S/MIME-signed email is opened in Microsoft Outlook. This issue, which has been originally reported in 2008, has been revisited and timing differences make it possible to identify open and closed ports on internal networks.
