See https://lists.debian.org/debian-lts/2021/01/msg00016.html for
further information.

For Debian 9 stretch, this problem has been documented in version
1:9+2021.01.23 of the debian-security-support package.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
