Microsoft Outlook Security Feature Bypass Vulnerability

Microsoft Outlook 2007, Microsoft Outlook 2010, Microsoft Outlook 2013, Microsoft Outlook 2016, and Microsoft Office 2016 Click-to-Run allow an elevation of privilege vulnerability due to how the format of incoming message is validated, aka "Microsoft Outlook Elevation of Privilege Vulnerability".

The S/MIME specification allows a Cipher Block Chaining (CBC) malleability-gadget attack that can indirectly lead to plaintext exfiltration, aka EFAIL.

Microsoft Outlook 2007 SP3, 2010 SP1 and SP2, 2013, and 2013 RT does not properly expand metadata contained in S/MIME certificates, which allows remote attackers to obtain sensitive network configuration and state information via a crafted certificate in an e-mail message, aka "S/MIME AIA Vulnerability."
