Application crash via oversized registration name
Published Feb 11, 2026 · Updated Feb 11, 2026
Buffer overflow in Nsasoft NetShareWatcher 1.5.8.0 allows local users to crash the application through the registration Name field. The registration dialog accepts a 1,000-character Name value and copies it without an effective length check, corrupting memory when OK is selected. Exploitation requires local interaction with the Windows GUI; the demonstrated consequence is termination of NetShareWatcher, not code execution.
