Red Hat Security Advisory

 

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

Advisory ID: RHSA-2014:1337-01

Product: Red Hat Enterprise Linux OpenStack Platform

Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-1337.html

Issue date: 2014-09-30

CVE Names: CVE-2014-5356

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

 

1. Summary:

 

Updated openstack-glance packages that fix one security issue and two bugs

are now available for Red Hat Enterprise Linux OpenStack Platform 5.0 for

Red Hat Enterprise Linux 7.

 

Red Hat Product Security has rated this update as having Moderate security

impact. A Common Vulnerability Scoring System (CVSS) base score, which

gives a detailed severity rating, is available from the CVE link in the

References section.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux OpenStack Platform 5.0 for RHEL 7 - noarch

 

3. Description:

 

OpenStack Image service (glance) provides discovery, registration, and

delivery services for disk and server images. It provides the ability to

copy or snapshot a server image, and immediately store it away. Stored

images can be used as a template to get new servers up and running quickly

and more consistently than installing a server operating system and

individually configuring additional services.

 

It was discovered that the image_size_cap configuration option in glance

was not honored. An authenticated user could use this flaw to upload an

image to glance and consume all available storage space, resulting in a

denial of service. (CVE-2014-5356)

 

This update also fixes the following bugs:

 

* Uploading an image to glance that exceeded the user's current quota

setting was rejected, but no message was added to the glance API log to

indicate this. This update fixes this bug, and such events are now logged

as INFO messages in the glance API log. (BZ#1055550)

 

* Whenever the 'x-image-meta-store' header was passed to glance-api, the

service would check whether the value was a valid store instead of a valid

scheme. However, the rest of the store library uses the scheme to identify

the store that should be used; this prevented the use of this feature.

Glance now verifies that the value of 'x-image-meta-store' is a valid

scheme instead of a valid store name. (BZ#1130622)

 

All openstack-glance users are advised to upgrade to these updated

packages, which correct these issues.

 

4. Solution:

 

Before applying this update, make sure all previously released errata

relevant to your system have been applied.

1055550 - glance: no error reported in api.log when image create is killed on quota

1130622 - Glance `--store` checks on store name instead of scheme

1131770 - CVE-2014-5356 openstack-glance: Glance store disk space exhaustion
