The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2553 advisory.

    Open vSwitch provides standard network bridging functions and support for the OpenFlow protocol for remote     per-flow control of traffic.

    Security Fix(es):

    * An unsigned int wrap around leading to a buffer over-read was found when parsing     OFPT_QUEUE_GET_CONFIG_REPLY messages in Open vSwitch (OvS). An attacker could use this flaw to cause a     remote DoS. (CVE-2017-9214)

    * In Open vSwitch (OvS), while parsing an OpenFlow role status message there is a call to the abort()     function 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-2017-9263)

    * A buffer over-read flaw was found in Open vSwitch (OvS) while parsing the group mod OpenFlow messages     sent from the controller. An attacker could use this flaw to cause a Denial of Service (DoS).
    (CVE-2017-9265)

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)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In Open vSwitch (OvS) v2.7.0, there is a 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`.
    (CVE-2017-9265)

Note that Nessus relies on the presence of the package as reported by the vendor.
