CVE-2014-5251

Status Candidate

Overview

The MySQL token driver in OpenStack Identity (Keystone) 2014.1.x before 2014.1.2.1 and Juno before Juno-3 stores timestamps with the incorrect precision, which causes the expiration comparison for tokens to fail and allows remote authenticated users to retain access via an expired token.

Red Hat Security Advisory 2014-1122-01
Posted Sep 2, 2014
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2014-1122-01 - The OpenStack Identity service authenticates and authorizes OpenStack users by keeping track of users and their permitted activities. The Identity service supports multiple forms of authentication, including user name and password credentials, token-based systems, and AWS-style logins. It was found that the MySQL token driver did not correctly store token expiration times, which prevented manual token revocation. Only OpenStack Identity setups configured to make use of revocation events were affected.
