The Microsoft Office application installed on the remote macOS or Mac OS X host is missing a security update. It is, therefore, affected by the following vulnerability:

  - 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. If   the current user is logged on with administrative user rights, an   attacker could take control of the affected system. An attacker   could then install programs; view, change, or delete data; or   create new accounts with full user rights. Users whose accounts   are configured to have fewer user rights on the system could be   less impacted than users who operate with administrative user   rights.

  Exploitation of the vulnerability requires that a user   open a specially crafted file with an affected version of   Microsoft Excel. In an email attack scenario, an attacker could   exploit the vulnerability by sending the specially crafted file   to the user and convincing the user to open the file. In a   web-based attack scenario, an attacker could host a website (or   leverage a compromised website that accepts or hosts user-provided   content) containing a specially crafted file designed to exploit   the vulnerability. An attacker would have no way to force users   to visit the website. Instead, an attacker would have to convince   users to click a link, typically by way of an enticement in an   email or instant message, and then convince them to open the   specially crafted file. (CVE-2018-8597)

  - An information disclosure vulnerability exists when Microsoft   Excel software reads out of bound memory due to an uninitialized   variable, which could disclose the contents of memory. An attacker   who successfully exploited the vulnerability could view out of   bound memory.

  Exploitation of the vulnerability requires that a user open a   specially crafted file with an affected version of Microsoft Excel   software. (CVE-2018-8627)

  - A remote code execution vulnerability exists in Microsoft   PowerPoint 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. If the current user is logged on with administrative   user rights, an attacker could take control of the affected system.   An attacker could then install programs; view, change, or delete   data; or create new accounts with full user rights. Users whose   accounts are configured to have fewer user rights on the system   could be less impacted than users who operate with administrative   user rights.

  Exploitation of the vulnerability requires that a user open a   specially crafted file with an affected version of Microsoft   Office PowerPoint software. In an email attack scenario, an   attacker could exploit the vulnerability by sending the specially   crafted file to the user and convincing the user to open the file.
  In a web-based attack scenario, an attacker could host a website   (or leverage a compromised website that accepts or hosts   user-provided content) that contains a specially crafted file   designed to exploit the vulnerability. An attacker would have no   way to force users to visit the website. Instead, an attacker   would have to convince users to click a link, typically by way of   an enticement in an email or instant message, and then convince   them to open the specially crafted file. (CVE-2018-8628)
