OpenStack Nova denial of service through compressed disk images
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
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.
