HighCVSS 8.4/10Last modified Jun 17, 2026

Description

Multi Emulator Super System 0.154-3.1 contains a buffer overflow vulnerability in the gamma parameter handling that allows local attackers to crash the application or execute arbitrary code. Attackers can supply an oversized gamma parameter value to overflow the stack buffer and overwrite the instruction pointer with a controlled address to achieve code execution.
