CVE-2014-3517
OpenStack Compute (Nova) Information Disclosure Through Timing Differences in Metadata Request Responses
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.

Action Type Old Value New Value Changed Description A side-channel timing attack flaw was found in Nova. An attacker could possibly use this flaw to guess valid instance ID signatures, giving them access to details of another instance, by analyzing the response times of requests for instance metadata. This issue only affected configurations that proxy metadata requests via Neutron. 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.
