The Microsoft Outlook application installed on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :- A remote code execution vulnerability exists in Microsoft Outlook 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 System 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-2020-16947)
- A denial of service vulnerability exists in Microsoft Outlook software when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could cause a remote denial of service against a system. Exploitation of the vulnerability requires that a specially crafted email be sent to a vulnerable Outlook server. The security update addresses the vulnerability by correcting how Microsoft Outlook handles objects in memory. (CVE-2020-16949)
