1. Summary:
An update for openvswitch is now available for Red Hat Enterprise Linux
OpenStack Platform 7.0 (Kilo) for RHEL 7.
Red Hat Product Security has rated this update as having a security impact
of Important. 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.
2. Relevant releases/architectures:
Red Hat Enterprise Linux OpenStack Platform 7.0 for RHEL 7 - noarch, x86_64
3. Description:
Open vSwitch provides standard network bridging functions and support for
the OpenFlow protocol for remote per-flow control of traffic.
Security Fix(es):
* A buffer overflow flaw was discovered in the OVS processing of MPLS
labels. A remote attacker able to deliver a frame containing a malicious
MPLS label that would be processed by OVS could trigger the flaw and use
the resulting memory corruption to cause a denial of service (DoS) or,
possibly, execute arbitrary code. (CVE-2016-2074)
Red Hat would like to thank the Open vSwitch project for reporting this
issue. Upstream acknowledges Kashyap Thimmaraju and Bhargava Shastry as the
