Descriptions

The "process-execute" and "process-spawn" procedures did not free memory correctly when the execve() call failed, resulting in a memory leak. This could be abused by an attacker to cause resource exhaustion or a denial of service. 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" no liberan correctamente la memoria cuando falla la llamada execve(), resultando en una perdida de memoria. Esto podría ser aprovechado por un atacante para provocar un agotamiento de recursos o una denegación de servicio. Esto afecta a todas las versión de CHICKEN hasta la 4.11 inclusive (esto será fijado en la versión 4.12 y 5.0, que aún no se ha liberado).
