GHSA-2w87-5qcj-j6gx · Severity: low · Ecosystem: pip — OpenStack Compute (Nova) Denial of service due to improper validation of virtual size of QCOW2 image
OpenStack Compute (Nova) Folsom, Grizzly, and Havana, when use_cow_images is set to False, does not verify the virtual size of a QCOW2 image, which allows local users to cause a denial of service (host file system disk consumption) by transferring an image with a large virtual size that does not contain a large amount of data from Glance. NOTE: this issue is due to an incomplete fix for CVE-2013-2096.
