Fedora 29: elfutils Security Update 2018-32c8599fe1
Summary
Elfutils is a collection of utilities, including stack (to show
backtraces), nm (for listing symbols from object files), size
(for listing the section sizes of an object or archive file),
strip (for discarding symbols), readelf (to see the raw ELF file
structures), elflint (to check for well-formed ELF files) and
elfcompress (to compress or decompress ELF sections).
Fixes CVE-2018-16062, CVE-2018-16402 and CVE-2018-16403. unstrip: Handle
SHT_GROUP sections. strip: Handle mixed (out of order) allocated/non-allocated
sections. elfcompress: Don't rewrite input file if no section data needs
updating. Try harder to keep same file mode bits (suid) on rewrite. libelf,
libdw and all tools now handle extended shnum and shstrndx correctly.
