V1:
This patch is to fix the issue that StandaloneMmCore fails to detect
uncompressed inner FV.
PR: https://github.com/tianocore/edk2/pull/4943
V2:
Based on V1, fix some other issues
1. Add Missing object size checks before casting pointers to header types
a. InnerFvHeader = (EFI_FIRMWARE_VOLUME_HEADER *)SectionData;
This is introduced in V1, add the size check on SectionDataSize against
EFI_FIRMWARE_VOLUME_HEADER
b. Section = (EFI_COMMON_SECTION_HEADER *)(FileHeader + 1);
Use FfsFindSection instead of FfsFindSectionData to avoid pointer casting.
2. Fix potential memory leak issue that ScratchBuffer is not freed when page
allocation for DstBuffer fails.
PR: https://github.com/tianocore/edk2/pull/4965
V3:
1. Separate patch per individual issue fix on patch V2.
2. Fix one more issue: Limit FwVol encapsulation section recursion in
MmCoreFfsFindMmDriver().
