Win32k Elevation of Privilege Vulnerability

The remote Windows host is missing security update 5006674. It is, therefore, affected by multiple vulnerabilities

The remote Windows host is missing security update 5006667.
It is, therefore, affected by multiple vulnerabilities:

  - A session spoofing vulnerability exists. An attacker can     exploit this to perform actions with the privileges of     another user. (CVE-2021-36970, CVE-2021-40455)

  - A denial of service (DoS) vulnerability. An attacker can     exploit this issue to cause the affected component to     deny system or application services. (CVE-2021-36953,     CVE-2021-40463)

  - A security feature bypass vulnerability exists. An     attacker can exploit this and bypass the security     feature and perform unauthorized actions compromising     the integrity of the system/application.
    (CVE-2021-40460, CVE-2021-41338)

  - An elevation of privilege vulnerability. An attacker can     exploit this to gain elevated privileges.

  - An information disclosure vulnerability. An attacker can     exploit this to disclose potentially sensitive     information. (CVE-2021-38662, CVE-2021-38663,     CVE-2021-40454, CVE-2021-40475, CVE-2021-41332,     CVE-2021-41343)

  - A remote code execution vulnerability. An attacker can     exploit this to bypass authentication and execute     unauthorized arbitrary commands. (CVE-2021-40461,     CVE-2021-40462, CVE-2021-40465, CVE-2021-41330,     CVE-2021-41331, CVE-2021-41340, CVE-2021-41342)
