Why these techniques?

Heap buffer overflow in vmir's WASM parser (wasm_call) triggered remotely by crafted WASM file enables code execution or DoS, facilitating exploitation of public-facing applications (T1190), client execution (T1203), remote services (T1210), and application exploitation for endpoint DoS (T1499.004).
