SaltStack 3004.1 Security Issue

SaltStack released an update today:
https://saltproject.io/security_announcements/salt-security-advisory-release-june-21st-2022/

Security Onion currently uses SaltStack 3004.1. However, we don't use PAM authentication from within Salt so this security issue should not affect our installations.

We do have plans to update to Salt 3004.2 in the upcoming 2.3.140 release:
