Windows Win32k Elevation of Privilege Vulnerability

The remote Windows host is missing security update 4601319.
It is, therefore, affected by multiple vulnerabilities :

  - An information disclosure vulnerability. An attacker can     exploit this to disclose potentially sensitive     information. (CVE-2021-1734, CVE-2021-24076,     CVE-2021-24079, CVE-2021-24084, CVE-2021-24106)

  - A denial of service (DoS) vulnerability. An attacker can     exploit this issue to cause the affected component to     deny system or application services. (CVE-2021-24075,     CVE-2021-24080, CVE-2021-24086, CVE-2021-24098)

  - A remote code execution vulnerability. An attacker can     exploit this to bypass authentication and execute     unauthorized arbitrary commands. (CVE-2021-1722,     CVE-2021-24074, CVE-2021-24077, CVE-2021-24081,     CVE-2021-24083, CVE-2021-24088, CVE-2021-24091,     CVE-2021-24093, CVE-2021-24094)

  - An elevation of privilege vulnerability. An attacker can     exploit this to gain elevated privileges.
    (CVE-2021-1698, CVE-2021-1727, CVE-2021-1732,     CVE-2021-24096, CVE-2021-24102, CVE-2021-24103,     CVE-2021-25195)

  - 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-2021-1731,     CVE-2021-24082)
