Synopsis: Moderate: openstack-nova security and bug fix update

Advisory ID: RHSA-2013:1199-01

Product: Red Hat OpenStack

Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-1199.html

Issue date: 2013-09-03

CVE Names: CVE-2013-2256 CVE-2013-4179 CVE-2013-4185

CVE-2013-4261

=====================================================================

 

1. Summary:

 

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.

 

2. Relevant releases/architectures:

 

OpenStack 3 - noarch

 

3. Description:

 

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.
