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

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

- Ubuntu 19.10
- Ubuntu 19.04
- Ubuntu 18.04 LTS

Summary:

USN-4189-1 introduced a regression in DPDK.

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

Details:

USN-4189-1 fixed a vulnerability in DPDK. The new version introduced a
regression in certain environments. This update fixes the problem.

Original advisory 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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 19.10:
  dpdk                            18.11.5-0ubuntu0.19.10.1

Ubuntu 19.04:
  dpdk                            18.11.5-0ubuntu0.19.04.1

Ubuntu 18.04 LTS:
  dpdk                            17.11.9-0ubuntu18.04.1

This update uses a new upstream release, which includes additional bug
fixes. In general, a standard system update will make all the necessary
changes.
