"Georgi Guninski discovered that APT relied on GnuPG argument order and
did not check GPG subkeys when validating imported keyrings via
apt-key net-update. While it appears that a man-in-the-middle attacker
cannot exploit this, as a hardening measure this update adjusts
apt-key to validate all subkeys when checking for key collisions.

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