Description Marvin Häuser 2021-04-12 09:56:50 UTC 
EFI_PEI_FFS_FIND_SECTION_DATA2[1] and EFI_PEI_FFS_FIND_SECTION_DATA3[2] return section data without their corresponding sizes. This makes secure parsing of the data impossible. This is an issue with the UEFI PI specification and is submitted mainly for discussion/feedback and tracking reasons.
