Debian DSA-4056-1 : nova - security update

medium Nessus Plugin ID 105088

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the nova packages.

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