"This update for openvswitch fixes the following issues :

  - CVE-2017-9263: OpenFlow role status message can cause a
    call to abort() leading to application crash
    (bsc#1041470)

  - CVE-2017-9265: Buffer over-read while parsing message
    could lead to crash or maybe arbitrary code execution
    (bsc#1041447)

  - Do not restart the ovs-vswitchd and ovsdb-server
    services on package updates (bsc#1002734)

  - Do not restart the ovs-vswitchd, ovsdb-server and
    openvswitch services on package removals. This
    facilitates potential future package moves but also
    preserves connectivity when the package is removed
    (bsc#1050896)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
