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 in Microsoft Office software due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit these, by convincing a user to open a specially crafted document file, to execute arbitrary code in the context of the current user. (CVE-2017-0020, CVE-2017-0030, CVE-2017-0031)

- An information disclosure vulnerability exists in Microsoft Office due to improper disclosure of memory contents. An unauthenticated, remote attacker can exploit this to disclose sensitive system memory information by convincing a user to open a specially crafted document file. (CVE-2017-0027)

- A denial of service vulnerability exists in Microsoft Office that allows an unauthenticated, remote attacker to cause Office to stop responding by convincing a user to open a specially crafted document file.
(CVE-2017-0029)

- An out-of-bounds read error exists in Microsoft Office due to an uninitialized variable. A local attacker can exploit this to disclose memory contents by opening a specially crafted document file. (CVE-2017-0105)

- A flaw exists in Microsoft Lync for Mac due to improper validation of X.509 certificates. A man-in-the-middle attacker can exploit this, by spoofing a TLS/SSL server via a certificate that appears valid, to disclose or manipulate transmitted data. (CVE-2017-0129)

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 Lync for Mac 2011.
