CVE-2016-20040

TiEmu 3.03-nogdb+dfsg-3 contains a buffer overflow vulnerability in the ROM parameter handling that allows local attackers to crash the application or execute arbitrary code. Attackers can supply an oversized ROM parameter to the tiemu command-line interface to overflow the stack buffer and overwrite the instruction pointer with malicious addresses.

Summary		(es) TiEmu 3.03-nogdb+dfsg-3 contiene una vulnerabilidad de desbordamiento de búfer en el manejo de parámetros ROM que permite a atacantes locales bloquear la aplicación o ejecutar código arbitrario. Los atacantes pueden suministrar un parámetro ROM sobredimensionado a la interfaz de línea de comandos de tiemu para desbordar el búfer de pila y sobrescribir el puntero de instrucción con direcciones maliciosas.
