title: 'Potential Nova denial of service through compressed disk images'
|
|
|
|
description: 'Bernhard M. Wiedemann from SUSE reported a vulnerability in Nova''s
|
|
control of the size of disk images. By using malicious compressed qcow2 disk images,
|
|
an authenticated user may consume large amounts of disk space for each image, potentially
|
|
resulting in a Denial of Service attack on Nova compute nodes (CVE-2013-4463). While
|
|
fixing this issue, Pádraig Brady from Red Hat additionally discovered that OSSA
|
|
2013-012 did not fully address CVE-2013-2096 in the non-default case where use_cow_images=False,
|
|
and malicious qcow images are being transferred from Glance. In that specific case,
|
|
an authenticated user could still consume large amounts of disk space for each instance
|
|
using the malicious image, potentially also resulting in a Denial of Service attack
|
|
on Nova compute nodes (CVE-2013-4469). The provided fixes address both issues.'
