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)

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)

An update for openvswitch is now available for Fast Datapath for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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

The following packages have been upgraded to a later upstream version:
openvswitch (2.7.2). (BZ#1472854)

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 was found in the Open vSwitch (OvS) firewall implementation. This flaw can be triggered by parsing a specially crafted TCP, UDP, or IPv6 packet. A remote attack could use this flaw to cause a Denial of Service (DoS). (CVE-2017-9264)

* 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).

This update was imported from the SUSE:SLE-12-SP3:Update update project.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2692 advisory.

  - openvswitch: Integer underflow in the ofputil_pull_queue_get_config_reply10 function (CVE-2017-9214)

  - openvswitch: Invalid processing of a malicious OpenFlow role status message (CVE-2017-9263)

  - openvswitch: Buffer over-read while parsing the group mod OpenFlow message (CVE-2017-9265)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - openvswitch: Buffer over-read while parsing the group mod OpenFlow message (CVE-2017-9265)

  - In Open vSwitch (OvS) 2.7.0, 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-2017-9214)

  - In Open vSwitch (OvS) 2.7.0, 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)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
