OpenStack Security Advisory: 2014-015
CVE: CVE-2014-0204
Date: May 21, 2014
Title: Keystone user and group id mismatch
Reporter: Michael Stancampiano (IBM)
Products: Keystone
Versions: 2014.1

Michael Stancampiano from IBM reported a vulnerability in Keystone.
Someone with write access to the user and group repository (such as the
LDAP directory server) may willingly or unwillingly grant additional
rights by picking the same IDs for users and groups, resulting in roles
assigned to a group being assigned to the affected user even if he is
not a member of this group. Only Keystone setups using LDAP for the
Identity driver are affected.

Juno (development branch) fixes:

Icehouse fix:

This fix will be included in the juno-1 development milestone and in
a future 2014.1.1 release.
