CVE-2017-20225

TiEmu 2.08 and prior contains a stack-based buffer overflow vulnerability that allows attackers to execute arbitrary code by exploiting inadequate boundary checks on user-supplied input. Attackers can trigger the overflow through command-line arguments passed to the application, leveraging ROP gadgets to bypass protections and execute shellcode in the application context.

Summary		(es) TiEmu 2.08 y versiones anteriores contiene una vulnerabilidad de desbordamiento de búfer basado en pila que permite a los atacantes ejecutar código arbitrario explotando comprobaciones de límites inadecuadas en la entrada proporcionada por el usuario. Los atacantes pueden desencadenar el desbordamiento a través de argumentos de línea de comandos pasados a la aplicación, aprovechando gadgets ROP para eludir protecciones y ejecutar shellcode en el contexto de la aplicación.
