Detail

Problem Description:

An update for openvswitch is now available for Red Hat Enterprise Linux OpenStack Platform 6.0 (Juno) 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 6.0 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 original reporters.
