Vulnerability triggering, via opening two specially crafted text files as input to notepad++.
Affected Versions:
Notepad++ versions 8.4.9 (32-bit) and before.

QID Detection Logic(Authenticated):
This QID checks for vulnerable version of NotePad ++ by checking the exe file.

When notepad++ opens any file it calls a function addHotSpot which creates heap memory with new operator and stores the return address in wide text variable. Since it requests for large allocation, new returns bad alloc which is not handled in notepad++ and results in DoS.
