RHSA-2017:1595 - Security Advisory

Topic

An update for openstack-nova and python-novaclient is now available for Red Hat OpenStack Platform 10.0 (Newton).

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

OpenStack Compute (nova) launches and schedules large networks of virtual machines, creating a redundant and scalable cloud computing platform. Compute provides the software, control panels, and APIs required to orchestrate a cloud, including running virtual machine instances and controlling access through users and projects.

python-novaclient is the python client for the OpenStack Nova API. The client's Python API (the novaclient module) and command-line script (nova) both implement 100% of the OpenStack Nova API.

The following packages have been upgraded to a later upstream version: python-novaclient (6.0.0), openstack-nova (14.0.6). (BZ#1421265, BZ#1431802, BZ#1429924, BZ#1454629, BZ#1454630)

Security Fix(es):

• An information exposure issue was discovered in OpenStack Compute's exception_wrapper.py. Legacy notification exception contexts appearing in ERROR-level logs could include sensitive information such as account passwords and authorization tokens. (CVE-2017-7214)
