Summary
Red Hat Security Advisory: openstack-nova security and bug fix update

Notes

Topic
Updated openstack-nova packages that fix multiple security issues and various bugs are now available for Red Hat OpenStack 3.0. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
Details
The openstack-nova packages provide OpenStack Compute (Nova), which provides services for provisioning, managing, and using virtual machine instances. It was found that the fixes for CVE-2013-1664 and CVE-2013-1665, released via RHSA-2013:0657, did not fully correct the issues in the Extensible Markup Language (XML) parser used by Nova. A remote attacker could use this flaw to send a specially-crafted request to a Nova API, causing Nova to consume an excessive amount of CPU and memory, or possibly crash. (CVE-2013-4179) A denial of service flaw was found in the way Nova handled network source security group policy updates. An authenticated user could send a large number of server creation operations, causing nova-network to become unresponsive. (CVE-2013-4185) An information disclosure flaw and a resource limit bypass were found in the way Nova handled virtual hardware templates (flavors). These allowed tenants to show and boot other tenants' flavors and bypass resource limits enforced via the os-flavor-access:is_public property. (CVE-2013-2256) It was discovered that, in some configurations, certain messages in console-log could cause nova-compute to become unresponsive, resulting in a denial of service. (CVE-2013-4261) Red Hat would like to thank the OpenStack project for reporting CVE-2013-2256 and CVE-2013-4185. Upstream acknowledges hzrandd from NetEase as the original reporter of CVE-2013-2256, and Vishvananda Ishaya from Nebula as the original reporter of CVE-2013-4185. Upstream also acknowledges Ken'ichi Ohmichi from NEC for providing a corrected fix for CVE-2013-2256. The CVE-2013-4179 issue was discovered by Grant Murphy of the Red Hat Product Security Team, and CVE-2013-4261 was discovered by Jaroslav Henner of Red Hat. This update also fixes a number of bugs in openstack-nova. Additionally, openstack-nova has been rebased to the latest stable release 2013.1.3. (BZ#993100) All users of openstack-nova are advised to upgrade to these updated packages, which correct these issues. After installing the updated packages, the running Nova services will be restarted automatically.
