Synopsis: Important: openstack-nova security, bug fix, and enhancement update

Advisory ID: RHSA-2015:0844-01

Product: Red Hat Enterprise Linux OpenStack Platform

Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-0844.html

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

 

1. Summary:

 

Updated OpenStack Compute (nova) packages that fix three security issues,

several bugs, and add various enhancements are now available for Red Hat

Enterprise Linux OpenStack Platform 5.0 for Red Hat Enterprise Linux 6.

 

Red Hat Product Security has rated this update as having Important 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:

 

Red Hat Enterprise Linux OpenStack Platform 5.0 for RHEL 6 - noarch

 

3. Description:

 

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.

 

It was discovered that the OpenStack Compute (nova) console websocket did

not correctly verify the origin header. An attacker could use this flaw to

conduct a cross-site websocket hijack attack. Note that only Compute setups

with VNC or SPICE enabled were affected by this flaw. (CVE-2015-0259)

 

A denial of service flaw was found in the way OpenStack Compute (nova)

looked up VM instances based on an IP address filter. An attacker with

sufficient privileges on an OpenStack installation with a large amount of

VMs could use this flaw to cause the main nova process to block for an

extended amount of time. (CVE-2014-3708)

 

A flaw was found in the OpenStack Compute (nova) VMWare driver, which could

allow an authenticated user to delete an instance while it was in the

resize state, causing the instance to remain on the back end. A malicious

user could use this flaw to cause a denial of service by exhausting all

available resources on the system. (CVE-2014-8333)

 

Red Hat would like to thank the OpenStack project for reporting the

CVE-2015-0259 and CVE-2014-3708 issues. Upstream acknowledges Brian

Manifold of Cisco and Paul McMillan of Nebula as the original reporters of

CVE-2015-0259, and Mohammed Naser from Vexxhost as the original reporter of

CVE-2014-3708.

 

In addition to the above issues, this update also addresses several bugs

and adds various enhancements, which are documented in the Red Hat

Enterprise Linux OpenStack Platform Technical Notes (see References

section).

 

All openstack-nova users are advised to upgrade to these updated packages,

which correct these issues and add these enhancements.
