A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 12.04 LTS

Summary

Two security issues were fixed in OpenStack Keystone.

Software Description

  • keystone - OpenStack identity service

Details

Dolph Mathews discovered that OpenStack Keystone did not properly restrict to administrative users the ability to update users’ tenants. A remote attacker that can reach the administrative API can use this to add any user to any tenant. (CVE-2012-3542)

Derek Higgins discovered that OpenStack Keystone did not properly implement token expiration. A remote attacker could use this to continue to access an account that has been disabled or has a changed password. (CVE-2012-3426)
