"The remote MiracleLinux 9 host has packages installed that are affected by a vulnerability as referenced in the
AXSA:2024-7682:03 advisory.

    * A vulnerability was found in Unbound due to incorrect default permissions,
    allowing any process outside the unbound group to modify the unbound runtime
    configuration. The default combination of the control-use-cert: no option with
    either explicit or implicit use of an IP address in the control-interface
    option could allow improper access. If a process can connect over localhost to
    port 8953, it can alter the configuration of unbound.service. This flaw allows
    an unprivileged local process to manipulate a running instance, potentially
    altering forwarders, allowing them to track all queries forwarded by the local
    resolver, and, in some cases, disrupting resolving altogether.
    To mitigate the vulnerability, a new file
    /etc/unbound/conf.d/remote-control.conf has been added and included in the
    main unbound configuration file, unbound.conf. The file contains two
    directives that should limit access to unbound.conf:
    control-interface: /run/unbound/control
    control-use-cert: yes
    For details about these directives, run man unbound.conf.
    Updating to the version of unbound provided by this advisory should, in most
    cases, address the vulnerability. To verify that your configuration is not
    vulnerable, use the unbound-control status | grep control command. If the
    output contains control(ssl) or control(namedpipe), your configuration is
    not vulnerable. If the command output returns only control, the configuration
    is vulnerable because it does not enforce access only to the unbound group
    members. To fix your configuration, add the line include:
    /etc/unbound/conf.d/remote-control.conf to the end of the file
    /etc/unbound/unbound.conf. If you use a custom
    /etc/unbound/conf.d/remote-control.conf file, add the new directives to this
    file. (CVE-2024-1488)
