"Adminer is an open source database management in a single PHP file. In
adminer from version 4.0.0 and before 4.7.9 there is a server-side
request forgery vulnerability. Users of Adminer versions bundling all
drivers (e.g. `adminer.php`) are affected.

For Debian 9 stretch, this problem has been fixed in version
4.2.5-3+deb9u2.

We recommend that you upgrade your adminer packages.

For the detailed security status of adminer please refer to its
security tracker page at:
https://security-tracker.debian.org/tracker/adminer

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.");
