Package        : nova
CVE ID         : CVE-2017-16239
Debian Bug     : 882009

George Shuklin from servers.com discovered that Nova, a cloud
computing fabric controller, did not correctly enforce its image- or
hosts-filters. This allowed an authenticated user to bypass those
filters by simply rebuilding an instance.

For the stable distribution (stretch), this problem has been fixed in
version 2:14.0.0-4+deb9u1.

We recommend that you upgrade your nova packages.

For the detailed security status of nova please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/nova
