"The remote MiracleLinux 7 host has packages installed that are affected by a vulnerability as referenced in the
AXSA:2016-832:08 advisory.

    systemd is a system and service manager for Linux, compatible with
    SysV and LSB init scripts. systemd provides aggressive parallelization
    capabilities, uses socket and D-Bus activation for starting services,
    offers on-demand starting of daemons, keeps track of processes using
    Linux cgroups, supports snapshotting and restoring of the system
    state, maintains mount and automount points and implements an
    elaborate transactional dependency-based service control logic. It can
    work as a drop-in replacement for sysvinit.
    Security issues fixed with this release:
    CVE-2016-7795
    The manager_invoke_notify_message function in systemd 231 and earlier
    allows local users to cause a denial of service (assertion failure and
    PID 1 hang) via a zero-length message received over a notify socket.
    Fixed bugs:
    * Previously, the udev device manager automatically enabled all memory banks on IBM z System
    installations. As a consequence, hot plug memory was enabled automatically, which was incorrect. With this
    update, system architecture checks have been added to the udev rules to address the problem. As a result,
    hot plug memory is no longer automatically enabled.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
