CVE-2013-6437

Publication date 6 March 2014

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

The libvirt driver in OpenStack Compute (Nova) before 2013.2.2 and icehouse before icehouse-2 allows remote authenticated users to cause a denial of service (disk consumption) by creating and deleting instances with unique os_type settings, which triggers the creation of a new ephemeral disk backing file.
