Description:

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. (bsc#1041470)
  • 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 ofputil_pull_ofp15_group_mod.(bsc#1041447)
  • 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. (bsc#1040543)

  • 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)
