Heap-based buffer overflow in Remote Desktop Client allows an unauthorized attacker to execute code over a network.

The remote Windows host is missing security update 5094122. It is, therefore, affected by multiple vulnerabilities

  - Integer overflow or wraparound in Windows HTTP.sys allows an unauthorized attacker to execute code over a     network. (CVE-2026-47291)

  - Heap-based buffer overflow in Remote Desktop Client allows an unauthorized attacker to execute code over a     network. (CVE-2026-42909, CVE-2026-42985, CVE-2026-42992, CVE-2026-44799, CVE-2026-44801, CVE-2026-47289,     CVE-2026-47653, CVE-2026-47654)

  - Heap-based buffer overflow in Microsoft Windows DNS allows an authorized attacker to elevate privileges     locally. (CVE-2026-41108)

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