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).
