The remote Windows host is missing security update 5099539. 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 FTP Service allows an unauthorized attacker to execute code over a     network. (CVE-2026-49172)

  - Improper validation of consistency within input in Windows Secure Kernel Mode allows an authorized     attacker to elevate privileges locally. (CVE-2026-42982)

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