Subject: [OSSA 2014-026] Multiple vulnerabilities in Keystone revocation events
(CVE-2014-5251, CVE-2014-5252, CVE-2014-5253)
OpenStack Security Advisory: 2014-026
CVE: CVE-2014-5251, CVE-2014-5252, CVE-2014-5253
Date: August 15, 2014
Title: Multiple vulnerabilities in Keystone revocation events
Reporter: Lance Bragstad (Rackspace) - CVE-2014-5252
Brant Knudson (IBM) - CVE-2014-5251, CVE-2014-5253
Products: Keystone
Versions: 2014.1 versions up to 2014.1.1
Description:
Lance Bragstad from Rackspace and Brant Knudson from IBM reported 3
vulnerabilities in Keystone revocation events. Lance Bragstad discovered
that UUID v2 tokens processed by the V3 API are incorrectly updated and
get their "issued_at" time regenerated (CVE-2014-5252). Brant Knudson
discovered that the MySQL token driver stores expiration dates
incorrectly which prevents manual revocation (CVE-2014-5251) and that
domain-scoped tokens don't get revoked when the domain is disabled
(CVE-2014-5253). Tokens impacted by one of these bugs may allow a user
to evade token revocation. Only Keystone setups configured to use
revocation events are affected.
Juno (development branch) fix:
