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).
