Description

OpenShift Enterprise by Red Hat is the company's cloud computing

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
