What is CVE-2016-20039?

The Multi Emulator Super System (MAME) versions 0.154-3.1 has a vulnerability due to improper handling of the gamma parameter, leading to a buffer overflow. This flaw enables local attackers to crash the application or potentially execute arbitrary code. By supplying an excessively large gamma parameter, an attacker can overflow the stack buffer, overwrite the instruction pointer, and gain control of execution flow. This presents significant risks for application integrity and security.
