Description Kurt Seifried 2013-03-15 19:54:53 UTC
Thierry Carrez (thierry@openstack.org) reports:

Title: Online validation of Keystone PKI tokens bypasses revocation check
Reporter: Guang Yee (HP)
Products: Keystone
Affects: Folsom

Description:
Guang Yee from HP reported a vulnerability in the revocation check for
Keystone PKI tokens. Those tokens are supposed to be validated locally
using cryptographic checks, but the user also has the option of asking
the server to validate them. In that case, the online verification of
PKI tokens would bypass the revocation check, potentially affirming
revocated tokens are still valid. Only setups making use of online
verification of PKI tokens are affected.

Proposed patches:
See attached patch. Unless a flaw is discovered in it, this patch will
be merged to Keystone stable/folsom branch on the public disclosure date.
