    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:
