The remote Windows host is missing security update 5063899. It is, therefore, affected by multiple vulnerabilities

  - Heap-based buffer overflow in Windows GDI+ allows an unauthorized attacker to execute code over a network.
    (CVE-2025-53766)

  - Missing synchronization in Windows Hyper-V allows an authorized attacker to deny service over an adjacent     network. (CVE-2025-49751)

  - Concurrent execution using shared resource with improper synchronization ('race condition') in Microsoft     Graphics Component allows an authorized attacker to elevate privileges locally. (CVE-2025-49743)

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