CVE-2013-2096 OpenStack Nova vulnerability
Title: OpenStack Nova vulnerability
Summary: Nova could be made to crash the system if instances used a specially
crafted image.
Loganathan Parthipan discovered that Nova did not verify the size of QCOW2
instance storage. An authenticated attacker could exploit this to cause a
denial of service by creating an image with a large virtual size with
little data, then filling the virtual disk.
Instructions: In general, a standard system update will make all the necessary changes.

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.

Michael Still ([email protected]) reports:
Title: Nova fails to verify image virtual size
Reporter: Loganathan Parthipan
Products: Nova
Affects: All versions
Loganathan Parthipan publicly reported a vulnerability in Nova. Nova
did not implement checking for the virtual size of a qcow2 image used
as ephemeral storage for instances. It is therefore possible for a
user to create an image which has a large virtual size, but little
data. Once the instance is created, the user can then proceed to fill
the virtual disk, and consume all available disk on the host node file
system.
