      "value": "An arbitrary memory overwrite vulnerability in the trusted memory of Asylo exists in versions prior to 0.6.0. As the ecall_restore function fails to validate the range of the output_len pointer, an attacker can manipulate the tmp_output_len value and write to an arbitrary location in the trusted (enclave) memory. We recommend updating Asylo to version 0.6.0 or later."

      "value": "Se presenta una vulnerabilidad de sobrescritura de memoria arbitraria en la memoria confiable de Asylo en versiones anteriores a 0.6.0. Como la funci\u00f3n ecall_restore presenta un fallo al comprobar el rango del puntero output_len, un atacante puede manipular el valor tmp_output_len y escribir en una ubicaci\u00f3n arbitraria en la memoria confiable (enclave). Recomendamos actualizar Asylo en las versiones 0.6. 0 o posteriores"
