CVE-2016-3366 →

📋 Description

A spoofing vulnerability exists when Microsoft Outlook does not strictly adhere to RFC2046, and improperly identifies the end of a MIME attachment. An improper MIME attachment ending may cause antivirus or antispam scanning to not work as intended. To exploit the vulnerability, an attacker could send a specially crafted email attachment to a user in an attempt to launch a social engineering attack, such as phishing. The security update addresses the vulnerability by correcting how Outlook determines the end of MIME messages.
