==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

Summary:

DPDK could be made to consume resources if it received specially crafted
input.

Software Description:
– dpdk: set of libraries for fast packet processing

Details:

Jason Wang discovered that DPDK incorrectly handled certain messages. An
attacker in a malicious container could possibly use this issue to cause
DPDK to leak resources, resulting in a denial of service.

changes.
