Vulnerability from csaf_redhat - Published: 2015-09-03 17:55 - Updated: 2024-11-14 18:11

Summary

Red Hat Security Advisory: openstack-nova security update

Severity

Moderate

Notes

Topic: Updated openstack-nova packages that fix one security issue are now available for Red Hat Enterprise Linux OpenStack Platform 7.0. 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 denial of service flaw was found in the OpenStack Compute (nova) instance migration process. Because the migration process does not terminate when an instance is deleted, an authenticated user could bypass user quota and deplete all available disk space by repeatedly re-sizing and deleting an instance. (CVE-2015-3241) Red Hat would like to thank the OpenStack project for reporting this issue. Upstream acknowledges George Shuklin of Webzilla LTD as the original reporter. All openstack-nova users are advised to upgrade to these updated packages, which correct this issue.
