An elevation of privilege vulnerability exists in Microsoft Office OLicenseHeartbeat task, where an attacker who successfully exploited this vulnerability could run this task as SYSTEM.To exploit the vulnerability, an authenticated attacker would need to place a specially crafted file in a specific location, thereby allowing arbitrary file corruption.The security update addresses the vulnerability by correcting how the process validates the log file., aka 'Microsoft Office Tampering Vulnerability'.

The Microsoft Office 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-2020-0759)

  - A security feature bypass vulnerability exists in Microsoft Outlook software when it improperly handles     the parsing of URI formats. The security feature bypass by itself does not allow arbitrary code execution.
    However, to successfully exploit the vulnerability, an attacker would have to use it in conjunction with     another vulnerability, such as a remote code execution vulnerability, to take advantage of the security     feature bypass vulnerability and run arbitrary code. (CVE-2020-0696)

  - An elevation of privilege vulnerability exists in Microsoft Office OLicenseHeartbeat task, where an     attacker who successfully exploited this vulnerability could run this task as SYSTEM. (CVE-2020-0697)
