- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 882009.
In Mitre's CVE dictionary: CVE-2017-16239.
- More information:
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.
