high Nessus Plugin ID 100295
New! Plugin Severity Now Using CVSS v3

Synopsis

An application installed on the remote macOS or Mac OS X host is affected by a remote code execution vulnerability.

Description

The Microsoft Office application installed on the remote macOS or Mac OS X host is missing a security update. It is, therefore, affected by a remote code execution vulnerability due to a failure to properly handle objects in memory. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted Office document or visit a specially crafted website, to execute arbitrary code in the context of the current user.

Solution

Microsoft has released patches for Microsoft Office for Mac 2011 and Microsoft Office 2016 for Mac.
