Synopsis

An application installed on the remote macOS or Mac OS X host is affected by multiple vulnerabilities.

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 multiple vulnerabilities :

- Multiple remote code execution vulnerabilities exist due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit these by convincing a user to visit a specially crafted website or open a specially crafted Office file, resulting in the execution of arbitrary code in the context of the current user. (CVE-2016-7213, CVE-2016-7228, CVE-2016-7229, CVE-2016-7231, CVE-2016-7232, CVE-2016-7234, CVE-2016-7235, CVE-2016-7236)

- An information disclosure vulnerability exists due to an out-of-bounds read error caused by an uninitialized variable. An unauthenticated, remote attacker can exploit this by convincing a user to open a specially crafted Office file, resulting in the disclosure of memory contents. (CVE-2016-7233)

Solution

Microsoft has released a set of patches for Microsoft Office for Mac 2011, Microsoft Office 2016 for Mac, Microsoft Excel for Mac 2011, Microsoft Excel 2016 for Mac, Microsoft Word for Mac 2011, and Microsoft Word 2016 for Mac.
