CVE-2017-15023 (opens in a new tab)How to fix?
Upgrade Debian:unstable 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:unstable relevant fixed versions and status.
read_formatted_entries in dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, does not properly validate the format count, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted ELF file, related to concat_filename.
