Package	Affected versions	Patched versions
nova PyPI	`≥ 2014.0.0, < 2014.1.2< 2013.2.4`	`2014.1.22013.2.4`
nova openstack	`= 2014.2.0≥ 2013.2, ≤ 2013.2.4≥ 2014.1, < 2014.1.2`	`2014.1.2`

Description

api/metadata/handler.py in OpenStack Compute (Nova) before 2013.2.4, 2014.x before 2014.1.2, and Juno before Juno-2, when proxying metadata requests through Neutron, makes it easier for remote attackers to guess instance ID signatures via a brute-force attack that relies on timing differences in responses to instance metadata requests.
