Descriptions

The "process-execute" and "process-spawn" procedures in CHICKEN Scheme used fixed-size buffers for holding the arguments and environment variables to use in its execve() call. This would allow user-supplied argument/environment variable lists to trigger a buffer overrun. This affects all releases of CHICKEN up to and including 4.11 (it will be fixed in 4.12 and 5.0, which are not yet released).

Los procedimientos "process-execute" y "process-spawn" en CHICKEN Scheme utilizaron búfers de tamaño fijo para mantener los argumentos y las variables de entorno para usar en su llamada execve(). Esto podría permitir que las listas de variable de argumento/entorno suministradas por el usuario desencadenaran un desbordamiento de búfer. Esto afecta a todas las versiones de CHICKEN hasta la 4.11 inclusive (esto será fijado en la versión 4.12 y 5.0, que aún no se han liberado).
