Summary

OpenShift Enterprise by Red Hat is the company's cloud computing Platform-as-a-Service (PaaS) solution designed for on-premise or private cloud deployments.
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 these issues. Upstream acknowledges Kashyap Thimmaraju and Bhargava Shastry as the original reporters of CVE-2016-2074.
This update includes the following images:
openshift3/openvswitch:v3.1.1.6-9 aep3_beta/openvswitch:v3.1.1.6-9 openshift3/node:v3.1.1.6-16 aep3_beta/node:v3.1.1.6-16
All openvswitch users are advised to upgrade to this updated package, which contains a backported patch to correct this issue.
