Description Kurt Seifried 2013-10-25 19:51:35 UTC
Thierry Carrez of the OpenStack project reports:

Title: Potential Nova denial of service through compressed disk images
Reporter: Pedraig Brady from Red Hat
Products: Nova
Affects: All versions

Description:
Pedraig 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. The provided fixes address both issues.

This issue was CVE SPLIT, please see Bz1023239 for the patches for this issue.
