high Nessus Plugin ID 141470

Language:

Synopsis

The Microsoft Office product installed on the remote host is affected by multiple vulnerabilities.

Description

The Microsoft Office product installed on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities:

 - A remote code execution vulnerability exists when the Base3D rendering engine handles memory. An attacker who successfully exploited the vulnerability would gain execution on a victim system. (CVE-2020-16918)

 - A remote code execution vulnerability exists in Microsoft Excel software when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. (CVE-2020-16929)

 - A security feature bypass vulnerability exists in Microsoft Word software when it fails to properly handle .LNK files. An attacker who successfully exploited the vulnerability could use a specially crafted file to perform actions in the security context of the current user. (CVE-2020-16933)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

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