If the system does not need to have an Avahi server which implements the DNS Service Discovery and Multicast DNS protocols, the avahi-autoipd and avahi packages can be uninstalled.
Automatic discovery of network services is not normally required for system functionality. It is recommended to remove this package to reduce the potential attack surface.
The following script can be run on the host to remediate the issue.
#!/bin/bash
# CAUTION: This remediation script will remove avahi-autoipd
# from the system, and may remove any packages
# that depend on avahi-autoipd. Execute this
# remediation AFTER testing on a non-production
# system!
if rpm -q --quiet "avahi-autoipd" ; then
yum remove -y "avahi-autoipd"
fi
The following playbook can be run with Ansible to remediate the issue.
