USN-1772-1: OpenStack Keystone vulnerability

20 March 2013

Under certain configurations, Keystone would allow unintended access over the network.




Guang Yee discovered that Keystone would not always perform all
verification checks when configured to use PKI. If the keystone server was
configured to use PKI and services or users requested online verification,
an attacker could potentially exploit this to bypass revocation checks.
Keystone uses UUID tokens by default in Ubuntu.

Update instructions

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

Ubuntu 12.10

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