On June 15, 2015, Ubuntu Security Notice USN-2457-1 outlined updates addressing security gaps in OpenStack Neutron networking services.
Several security issues were fixed in OpenStack Keystone.

Summary

Several security issues were fixed in OpenStack Keystone.

Software Description:

- keystone: OpenStack identity service

Details:

Steven Hardy discovered that OpenStack Keystone did not properly handle

chained delegation. A remove authenticated attacker could use this to

gain privileges by creating a new token with additional roles.

(CVE-2014-3476)

Jamie Lennox discovered that OpenStack Keystone did not properly validate

the project id. A remote authenticated attacker may be able to use this to

access other projects. (CVE-2014-3520)

Brant Knudson and Lance Bragstad discovered that OpenStack Keystone would

not always revoke tokens correctly. If Keystone were configured to use

revocation events, a remote authenticated attacker could continue to have

access to resources. (CVE-2014-5251, CVE-2014-5252, CVE-2014-5253)

Update Instructions

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 14.04 LTS:
  python-keystone                 1:2014.1.2.1-0ubuntu1.1

In general, a standard system update will make all the necessary changes.
