A remote code execution vulnerability exists in Microsoft Excel software when the software fails to properly handle objects in memory, aka "Microsoft Excel Remote Code Execution Vulnerability." This affects Office 365 ProPlus, Microsoft Office, Microsoft Excel. This CVE ID is unique from CVE-2018-8577.

The Microsoft Excel Products are missing security updates.
It is, therefore, affected by multiple vulnerabilities :

  - 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.  (CVE-2018-8574, CVE-2018-8577)

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. The security update addresses the vulnerability by   correcting how Microsoft Excel handles objects in memory   (CVE-2018-8574, CVE-2018-8577)
