Spoofing Vulnerability in Microsoft Office for MAC

A spoofing vulnerability exists when Microsoft Outlook for MAC does not properly handle the encoding and display of email addresses. This improper handling and display 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 for MAC displays encoded email addresses.
