cinder vulnerabilities
============================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.04

Summary:

Cinder could be made to crash or expose sensitive information.

Software Description:
- cinder: OpenStack storage service

Details:

Rongze Zhu discovered that the Cinder LVM driver did not zero out data
when deleting snapshots. This could expose sensitive information to
authenticated users when subsequent servers use the volume. (CVE-2013-4183)

Grant Murphy discovered that Cinder would allow XML entity processing. A
remote unauthenticated attacker could exploit this using the Cinder API to
cause a denial of service via resource exhaustion. (CVE-2013-4179,
CVE-2013-4202)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 13.04:
  python-cinder                   1:2013.1.3-0ubuntu2.1

In general, a standard system update will make all the necessary changes.
