.NET Framework Denial of Service Vulnerability

The Microsoft .NET Framework installation on the remote host is missing a security update. It is, therefore, affected by a denial of service vulnerability.

The remote Windows host is missing security update 5009585. It is, therefore, affected by multiple vulnerabilities:

  - A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute     unauthorized arbitrary commands.     (CVE-2022-21962, CVE-2022-21959, CVE-2022-21963,     CVE-2022-21960, CVE-2022-21928, CVE-2022-21874,     CVE-2022-21961, CVE-2022-21958, CVE-2022-21893,     CVE-2022-21892, CVE-2022-21878, CVE-2022-21851,     CVE-2022-21850, CVE-2022-21849, CVE-2022-21922)     
  - An elevation of privilege vulnerability. An attacker can exploit this to gain elevated privileges.

  - A denial of service (DoS) vulnerability. An attacker can exploit this issue to cause the affected component to deny system or application services.
    (CVE-2022-21911, CVE-2022-21889, CVE-2022-21890,       CVE-2022-21883, CVE-2022-21843, CVE-2022-21848)

The remote Windows host is missing security update 5009546.
It is, therefore, affected by multiple vulnerabilities:

  - A remote code execution vulnerability. An attacker can     exploit this to bypass authentication and execute     unauthorized arbitrary commands. (CVE-2022-21849,     CVE-2022-21850, CVE-2022-21851, CVE-2022-21874,     CVE-2022-21878, CVE-2022-21892, CVE-2022-21893,     CVE-2022-21922, CVE-2022-21928, CVE-2022-21958,     CVE-2022-21959, CVE-2022-21960, CVE-2022-21961,     CVE-2022-21962, CVE-2022-21963)

  - An information disclosure vulnerability. An attacker can     exploit this to disclose potentially sensitive     information. (CVE-2022-21876, CVE-2022-21880,     CVE-2022-21904, CVE-2022-21915)

  - 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.

  - A session spoofing vulnerability exists. An attacker can     exploit this to perform actions with the privileges of     another user. (CVE-2022-21836)

  - A denial of service (DoS) vulnerability. An attacker can     exploit this issue to cause the affected component to     deny system or application services. (CVE-2022-21843,     CVE-2022-21848, CVE-2022-21883, CVE-2022-21889,     CVE-2022-21890)
