Heap-based buffer overflow in Windows Media allows an authorized attacker to execute code locally.

The remote Windows host is missing security update 5055518. It is, therefore, affected by multiple vulnerabilities

  - Use after free in Windows Win32K - GRFX allows an unauthorized attacker to elevate privileges over a     network. (CVE-2025-26687)   
  - A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute     unauthorized arbitrary commands. (CVE-2025-27481)

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