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), and elflint (to check for well-formed elf files).
security fix(es): dwarf_getaranges in dwarf_getaranges.c in libdw in elfutils before 2018-08-18 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted file.(cve-2018-16062) dwarf_getaranges in dwarf_getaranges.c in libdw in elfutils before 2018-08-18 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted file.(cve-2018-16402) libdw in elfutils 0.173 checks the end of the attributes list incorrectly in dwarf_getabbrev in dwarf_getabbrev.c and dwarf_hasattr in dwarf_hasattr.c, leading to a heap-based buffer over-read and an application crash.(cve-2018-16403) divide-by-zero vulnerabilities in the function arlib_add_symbols() in arlib.c in elfutils 0.174 allow remote attackers to cause a denial of service (application crash) with a crafted elf file, as demonstrated by eu-ranlib, because a zero sh_entsize is mishandled.(cve-2018-18521) a heap-based buffer over-read was discovered in the function read_srclines in dwarf_getsrclines.c in libdw in elfutils 0.175.
A crafted input can cause segmentation faults, leading to denial-of-service, as demonstrated by eu-nm.(cve-2019-7149) an issue was discovered in elfutils 0.175.
A segmentation fault can occur in the function elf64_xlatetom in libelf/elf32_xlatetom.c, due to dwfl_segment_report_module not checking whether the dyn data read from a core file is truncated.

An arbitrary attacker may exploit this vulnerability to compromise the system.
