RedHat: RHSA-2016-0524:01 Important: openvswitch security update
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.
