Descriptions

In FreeBSD 13.0-STABLE before n246938-0729ba2f49c9, 12.2-STABLE before r370383, 11.4-STABLE before r370381, 13.0-RELEASE before p4, 12.2-RELEASE before p10, and 11.4-RELEASE before p13, the ggatec daemon does not validate the size of a response before writing it to a fixed-sized buffer allowing a malicious attacker in a privileged network position to overwrite the stack of ggatec and potentially execute arbitrary code.

En FreeBSD versiones 13.0-STABLE anteriores a n246938-0729ba2f49c9, 12.2-STABLE anteriores a r370383, 11.4-STABLE anteriores a r370381, 13.0-RELEASE anteriores a p4, 12.2-RELEASE anteriores a p10, y 11. 4-RELEASE anteriores a p13, el demonio ggatec no comprueba el tamaño de una respuesta antes de escribirla en un búfer de tamaño fijo, permitiendo a un atacante malicioso en una posición de red privilegiada sobrescribir la pila de ggatec y ejecutar potencialmente código arbitrario.
