Vulnerability from csaf_redhat - Published: 2015-12-21 18:43 - Updated: 2025-11-21 17:54Summary
Red Hat Security Advisory: openstack-nova secuity and bug fix advisory
Severity
Moderate
Notes
Topic: Updated OpenStack Compute packages that resolve one security issue
and a bug are now available for Red Hat Enterprise Linux OpenStack
Platform 5.0 for RHEL 7.
Red Hat Product Security has rated this update as having Moderate
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the References section.
Details: 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.
A vulnerability was discovered in the way OpenStack Compute (nova)
networking handled security group updates; changes were not applied to
already running VM instances. A remote attacker could use this flaw to
access running VM instances. (CVE-2015-7713)
Additional bug fixes include:
* In some cases, Compute did not start instances when RHEL was
installed with a locale other than en_US. The update ensures that
logging an exception no longer causes Unicode issues. (BZ#1190837)
All openstack-nova users are advised to upgrade to these updated
packages, which correct these issues and add these enhancements.
