Subject: DPDK security advisory for multiple vhost crypto issues

A set of vulnerabilities are fixed in DPDK:
- CVE-2020-14374
- CVE-2020-14375
- CVE-2020-14376
- CVE-2020-14377
- CVE-2020-14378

Some downstream stakeholders were warned in advance in order to coordinate the
release of fixes and reduce the vulnerability window.

Problem:
A malicious guest can harm the host using vhost crypto, this includes
executing code in host (VM Escape), reading host application memory
space to guest and causing partially denial of service in the host.

All users of the vhost library are strongly encouraged to upgrade as soon as
possible.

Thanks to "Ryan Hall <ryan.e.hall@...el.com>" for reporting the issues.
