JSON

The VMWare driver in OpenStack Compute (Nova) 2013.2 through 2013.2.2 does
not properly put VMs into RESCUE status, which allows remote authenticated
users to bypass the quota limit and cause a denial of service (resource
consumption) by requesting the VM be put into rescue and then deleting the
image.

Notes

Author	Note
jdstrand	requires use with unsupported VMware ESX driver. This is not compiled in to libvirt in the Ubuntu archive, which makes this code path unavailable in Ubuntu
