Issue date: 2016-03-30
CVE Names: CVE-2016-2074
=====================================================================
1. Summary:
An update for openvswitch is now available for Red Hat Enterprise Linux
OpenStack Platform 5.0 (Icehouse) 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 5.0 for RHEL 7 – noarch, x86_64
3. Description:
