The remote Windows host is missing security update 5099444. It is, therefore, affected by multiple vulnerabilities

  - Integer overflow or wraparound in Windows RDP allows an unauthorized attacker to execute code over a     network. (CVE-2026-58594)

  - Heap-based buffer overflow in Windows Message Queuing Queue Manager allows an unauthorized attacker to     execute code locally. (CVE-2026-54992)

  - Cleartext transmission of sensitive information in Windows Ancillary Function Driver for WinSock allows an     authorized attacker to disclose information locally. (CVE-2026-34346)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
