The remote Windows host is missing security update 5087471. It is, therefore, affected by multiple vulnerabilities

  - Stack-based buffer overflow in Windows Netlogon allows an unauthorized attacker to execute code over a     network. (CVE-2026-41089)

  - Heap-based buffer overflow in Windows Win32K - GRFX allows an authorized attacker to execute code locally.
    (CVE-2026-40403)

  - Heap-based buffer overflow in Windows Message Queuing allows an unauthorized attacker to execute code over     an adjacent network. (CVE-2026-34329)

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