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:

- A remote code execution vulnerability exists in Microsoft Word due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted file, to execute arbitrary commands in the security context of the current user. (CVE-2019-1201, CVE-2019-1205)

- An information disclosure vulnerability exists in Microsoft Windows Graphics due to improper handling of objects in memory. An authenticated, local attacker can exploit this, by running a specially crafted application to obtain information for further compromise of the system. (CVE-2019-1148, CVE-2019-1153)

- A remote code execution vulnerability exists in Windows font library due to improper handling of embedded fonts. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a specially crafted website or open a specially crafted file, to execute arbitrary commands. (CVE-2019-1149, CVE-2019-1151)

Solution

Microsoft has released a set of patches for Microsoft Office for Mac.
