CVE-2018-25220

Bochs 2.6-5 contains a stack-based buffer overflow vulnerability that allows attackers to execute arbitrary code by supplying an oversized input string to the application. Attackers can craft a malicious payload with 1200 bytes of padding followed by a return-oriented programming chain to overwrite the instruction pointer and execute shell commands with application privileges.

Summary		(es) Bochs 2.6-5 contiene una vulnerabilidad de desbordamiento de búfer basado en pila que permite a los atacantes ejecutar código arbitrario al proporcionar una cadena de entrada sobredimensionada a la aplicación. Los atacantes pueden crear una carga útil maliciosa con 1200 bytes de relleno seguidos de una cadena de programación orientada a retorno para sobrescribir el puntero de instrucción y ejecutar comandos de shell con privilegios de aplicación.
