"Security Fix(es) :
- A flaw was found in the way systemd handled empty
notification messages. A local attacker could use this
flaw to make systemd freeze its execution, preventing
further management of system services, system shutdown,
or zombie process collection via systemd.
(CVE-2016-7795)
Bug Fix(es) :
- 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."
