If the image is signed but not allowed by DB and the hash of
image is not found in DB/DBX, then the EFI_IMAGE_INFO_ACTION
of the load of said image should be set to,
EFI_IMAGE_EXECUTION_AUTH_SIG_NOT_FOUND, rather then being left
unset as EFI_IMAGE_EXECUTION_AUTH_UNTESTED.

It seems make sense.

Would you please:
1) Fila a Bugzilla - https://bugzilla.tianocore.org/
2) Describe what unit test you have done. Especially, if multiple cert list/data have been tested.
I ask this because we use a for-loop to check cert in list one by one.

Thank you
Yao Jiewen
