Security Advisory Moderate: openstack-cinder security update

Advisory: RHSA-2013:1198-1
Type: Security Advisory
Severity: Moderate
Issued on: 2013-09-03
Last updated on: 2013-09-03
Affected Products: Red Hat OpenStack 3.0
CVEs ( CVE-2013-4183


Updated openstack-cinder packages that fix two security issues 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.

The openstack-cinder packages provide OpenStack Volume (Cinder), which
provides services to manage and access block storage volumes for use by
virtual machine instances.

It was found that the fixes for CVE-2013-1664 and CVE-2013-1665, released
via RHSA-2013:0658, did not fully correct the issues in the Extensible
Markup Language (XML) parser used by Cinder. A remote attacker could use
this flaw to send a specially-crafted request to a Cinder API, causing
Cinder to consume an excessive amount of CPU and memory, or possibly crash.

A bug in the Cinder LVM driver prevented LVM snapshots from being securely
deleted in some cases, potentially leading to information disclosure to
other tenants. (CVE-2013-4183)

The CVE-2013-4202 issue was discovered by Grant Murphy of the Red Hat
Product Security Team.

Additionally, openstack-cinder has been rebased to the latest Grizzly
stable release 2013.1.3. (BZ#993094)

All users of openstack-cinder are advised to upgrade to these updated
packages, which correct these issues. After installing the updated
packages, the Cinder running services will be restarted automatically.


Before applying this update, make sure all previously released errata
relevant to your system have been applied.
