Kashyap Thimmaraju and Bhargava Shastry discovered a remotely triggerable buffer overflow vulnerability in openvswitch, a production quality, multilayer virtual switch implementation.

A remote attacker can take advantage of this flaw to cause a denial of service, or potentially, execution of arbitrary code.
