Solution

https://access.redhat.com/articles/11258

Summary

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.
