Updated openstack-glance packages that fix one security issue are now

available for Red Hat Enterprise Linux OpenStack Platform 7.0 (Kilo)

for RHEL 7.

 

Red Hat Product Security has rated this update as having a Low

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux OpenStack Platform 7.0 for RHEL 7 - noarch

 

3. Description:

 

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

delivery services for disk and server images. The service 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.

 

An authorization vulnerability in OpenStack Image service was discovered,

which allowed image-status manipulation using locations. By removing the

last location of an image, an authenticated user could change the status

from 'active' to 'queue'. A malicious tenant could exploit this flaw to

silently replace owned image data, regardless of its original creator or

visibility settings. Only environments with show_multiple_locations set

to true (not default) were affected. (CVE-2016-0757)

 

Red Hat would like to thank the OpenStack project for reporting this issue.

Upstream acknowledges Erno Kuvaja of HPE as the original reporter.

 

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

packages, which address this vulnerability.
