dpdk vulnerabilities
==========================================================================

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

- Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in DPDK.

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

Details:

Ryan Hall discovered that DPDK incorrectly handled vhost crypto. An
attacker inside a guest could use these issues to perform multiple attacks,
including denial of service attacks, obtaining sensitive information from
the host, and possibly executing arbitrary code on the host.

Update instructions:

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

Ubuntu 20.04 LTS:
  dpdk                            19.11.3-0ubuntu0.2

In general, a standard system update will make all the necessary changes.
