   An update that solves four vulnerabilities and has one
   errata is now available.


   This update for openvswitch fixes the following issues:

   * CVE-2017-9263: While parsing an OpenFlow role status message, there is a
     call to the abort() functio  for undefined role status reasons in the
     function `ofp_print_role_status_message` in `lib/ofp-print.c` that may
     be leveraged toward a remote DoS attack by a malicious switch.
   * CVE-2017-9265: Buffer over-read while parsing the group mod OpenFlow
     message sent from the controller in `lib/ofp-util.c` in the function
   * CVE-2017-9214: While parsing an OFPT_QUEUE_GET_CONFIG_REPLY type OFP 1.0
     message, there is a buffer over-read that is caused by an unsigned
     integer underflow in the function
     `ofputil_pull_queue_get_config_reply10` in `lib/ofp-util.c`.
   * CVE-2017-14970: In lib/ofp-util.c, there are multiple memory leaks while
     parsing malformed OpenFlow group mod messages.(bsc#1061310)

   * Do not stop the systemd service on package removals as this can break
     networking. Moreover, this allows us to easily update to more recent
     openvswitch releases without connectivity problems (bsc#1050896)
