            Bug ID: 23920
           Summary: elflint should check sanity check Chdr fields and
                    uncompressed data of compressed sections
           Product: elfutils
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: tools
          Assignee: unassigned at sourceware dot org
          Reporter: mark at klomp dot org
                CC: elfutils-devel at sourceware dot org
  Target Milestone: ---

elflint currently only checks that a section that has SHF_COMPRESSED set has a
Chdr. It doesn't check anything about the Chdr (does the ch_type make sense, is
the alignment a power of 2, does the data uncompress, etc.) nor whether the
other flags of the section make sense (it cannot be SHF_ALLOC, SHF_NOBITS).
