How to fix?

Upgrade Debian:9 elfutils to version 0.168-1+deb9u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream elfutils package and not the elfutils package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

libelf/elf_end.c in elfutils 0.173 allows remote attackers to cause a denial of service (double free and application crash) or possibly have unspecified other impact because it tries to decompress twice.
