    Several vulnerabilities were discovered in salt.
    
    CVE-2020-16846
    
        An unauthenticated user with network access to the Salt API can use
        shell injections to run code on the Salt-API using the SSH client
    
    CVE-2020-17490
    
        When using the functions create_ca, create_csr, and
        create_self_signed_cert in the tls execution module, it would not
        ensure the key was created with the correct permissions.
    
    CVE-2020-25592
    
        Properly validate eauth credentials and tokens along with their Access
        Control Lists – ACLs. Prior to this change, eauth was not properly
        validated when calling Salt SSH via the salt-api. Any value for “eauth”
        or “token” would allow a user to bypass authentication and make calls
        to Salt SSH
    
    For Debian 9 stretch, these problems have been fixed in version
    2016.11.2+ds-1+deb9u6.
    
    We recommend that you upgrade your salt packages.
