[edk2-devel] [PATCH 1/1] SecurityPkg/DxeImageVerificationLib: Set Action for failed unsigned image

[Samer El-Haj-Mahmoud]

Hi Jiewen, Jian, and Min,

Can you please review this patch? We have a corresponding UEFI Spec "code first" ECR (https://bugzilla.tianocore.org/show_bug.cgi?id=3561), and need to clarify a couple of cases in the code.

Thanks,
--Samer
