CVE-2017-15022 (opens in a new tab)How to fix?
Upgrade Debian:13 binutils to version 2.29.90.20180122-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream binutils package and not the binutils package as distributed by Debian.
See How to fix? for Debian:13 relevant fixed versions and status.
dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, does not validate the DW_AT_name data type, which allows remote attackers to cause a denial of service (bfd_hash_hash NULL pointer dereference, or out-of-bounds access, and application crash) via a crafted ELF file, related to scan_unit_for_symbols and parse_comp_unit.
