"The remote MiracleLinux 7 host has packages installed that are affected by a vulnerability as referenced in the
AXSA:2018-3100:04 advisory.

    * A command injection flaw was found in the NetworkManager integration script included in the DHCP client
    packages in Asianux Server. A malicious DHCP server, or an attacker on the local network able to spoof
    DHCP responses, could use this flaw to execute arbitrary commands with root privileges on systems using
    NetworkManager and configured to obtain network configuration using the DHCP protocol. (CVE-2018-1111)
    Asianux would like to thank Felix Wilhelm (Google Security Team) for reporting this issue.
