USN-1564-1: OpenStack Keystone vulnerability
13 September 2012
OpenStack Keystone did not properly handle user role changes
Releases
Packages
- keystone - OpenStack identity service
Details
Dolph Mathews discovered that when roles are granted and revoked to
users in Keystone, pre-existing tokens were not updated or invalidated
to take the new roles into account. An attacker could use this to
continue to access resources that have been revoked.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04
-
keystone
-
2012.1+stable~20120824-a16a0ab9-0ubuntu2.2
-
python-keystone
-
2012.1+stable~20120824-a16a0ab9-0ubuntu2.2
In general, a standard system update will make all the necessary changes.
