critical Nessus Plugin ID 249122

Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

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.
