[dpdk-announce] DPDK security advisory: CVE-2019-14818

[-- Attachment #1.1: Type: text/plain, Size: 1831 bytes --]

A vulnerability was fixed in DPDK.

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

Problem:
A malicious container which has direct access to the vhost-user socket can keep
sending messages which may cause leaking resources until resulting a DOS.

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