Description

The remote Windows host is missing security update 4571756.
It is, therefore, affected by multiple vulnerabilities :

- An elevation of privilege vulnerability exists when DirectX improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
(CVE-2020-1053, CVE-2020-1308)

- An elevation of privilege vulnerability exists when the Windows RSoP Service Application improperly handles memory. (CVE-2020-0648)
