George Rimar f01f65ea59 Recommit r285285 - [Object/ELF] - Fixed behavior when SectionHeaderTable->sh_size is too large. 
with fix: edited invalid-section-index2.elf input to pass the new check and 
fail on the same place it was intended to fail.

Original commit message:
Elf.h already has code checking that section table does not go past end of file.
Problem is that this check may not work on values greater than UINT64_MAX / Header->e_shentsize
because of calculation overflow.

Parch fixes the issue.
