Remedy

How to Mitigate: Upgrade to 3002.8, 3003.4, or 3004.1. Pre-seed the master’s public key on minions. NOTE: When upgrading your Salt infrastructure, first upgrade your Salt master packages before upgrading your Salt minion packages. Upgrading the minion packages first could result in loss of functionality.
