SaltStack CVE-2020-11651 and CVE-2020-11652

Two vulnerabilities in SaltStack were recently announced:

https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-11651

https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-11652

In the current Security Onion 16.04 platform, we use the standard SaltStack packages from the standard Ubuntu repositories.  Ubuntu is currently tracking these as follows:

https://people.canonical.com/~ubuntu-security/cve/2020/CVE-2020-11651.html

https://people.canonical.com/~ubuntu-security/cve/2020/CVE-2020-11652.html

We would expect that as soon as Ubuntu updates its packages, then a standard "soup" update would completely remove the vulnerabilities.

In the meantime, please keep in mind that Security Onion locks down the host-based firewall to only allow connections to the salt ports from known good salt minions.  If you feel the need for additional compensating controls, you may wish to add firewall restrictions to your network firewalls as well.
