USN-1851-1: python-keystoneclient vulnerability

3 June 2013

The python client library for Keystone did not properly verify expired PKI tokens.




Eoghan Glynn and Alex Meade discovered that python-keystoneclient did not
properly perform expiry checks for the PKI tokens used in Keystone. If
Keystone were setup to use PKI tokens (the default in Ubuntu 13.04), a
previously authenticated user could continue to use a PKI token for longer
than intended.

Update instructions

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

Ubuntu 13.04

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