- Summary
- OpenStack Nova denial of service through compressed disk images
- Details
-
OpenStack Compute (Nova) Folsom, Grizzly, and Havana does not properly verify the virtual size of a QCOW2 image, which allows local users to cause a denial of service (host file system disk consumption) via a compressed QCOW2 image. NOTE: this issue is due to an incomplete fix for CVE-2013-2096.
