How to fix?

Upgrade Debian:9 libarchive to version 3.2.2-2+deb9u3 or higher.

NVD Description

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

An improper link resolution flaw can occur while extracting an archive leading to changing modes, times, access control lists, and flags of a file outside of the archive. An attacker may provide a malicious archive to a victim user, who would trigger this flaw when trying to extract the archive. A local attacker may use this flaw to gain more privileges in a system.
