CVE-2016-2074

Status Candidate

Overview

Buffer overflow in lib/flow.c in ovs-vswitchd in Open vSwitch 2.2.x and 2.3.x before 2.3.3 and 2.4.x before 2.4.1 allows remote attackers to execute arbitrary code via crafted MPLS packets, as demonstrated by a long string in an ovs-appctl command.

Red Hat Security Advisory 2016-0615-01
Posted Apr 12, 2016
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2016-0615-01 - OpenShift Enterprise by Red Hat is the company's cloud computing Platform-as-a-Service 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 or, possibly, execute arbitrary code.

Red Hat Security Advisory 2016-0537-01 - Open vSwitch provides standard network bridging functions and support for the OpenFlow protocol for remote per-flow control of traffic. Security Fix: 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 or, possibly, execute arbitrary code.

Debian Security Advisory 3533-1
Posted Mar 29, 2016
Authored by Debian | Site debian.org

Debian Linux Security Advisory 3533-1 - Kashyap Thimmaraju and Bhargava Shastry discovered a remotely triggerable buffer overflow vulnerability in openvswitch, a production quality, multilayer virtual switch implementation. Specially crafted MPLS packets could overflow the buffer reserved for MPLS labels in an OVS internal data structure. A remote attacker can take advantage of this flaw to cause a denial of service, or potentially, execution of arbitrary code.
