Scientific Linux Security Update : systemd on SL7.x x86_64 (20161103)

medium Nessus Plugin ID 95862

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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.

Solution

Update the affected packages.
