Title: Missing expiration check in Keystone PKI token validation
Reporter: Eoghan Glynn (Red Hat)
Products/Affects: Keystone (Folsom only), python-keystoneclient (0.2.0+)

Description:
Eoghan Glynn from Red Hat reported a vulnerability in expiry checks for
PKI tokens in the Keystone authentication middleware. Expired tokens for
authenticated users could continue to be used, potentially resulting in
the bypass of intended security policies. The effect of PKI token
revocation is also reversed when the token expires, in the sense that a
revoked token is once again treated as being valid. Only setups using
PKI tokens are affected.

Note:
The affected code was added to Keystone in the Folsom release, but was
moved to python-keystoneclient during the Grizzly development cycle.


@maintainer(s): after the bump, in case we need to stabilize the package, please say explicitly if it is ready for the stabilization or not.

I already fixed sys-auth/keystone (check the changelog).  As far as python-keystoneclient goes, they haven't released a patch against 0.2.3.  If anyone can generate a patchset for it I'm all ears :D.
Comment 2 Matthew Thode ( prometheanfire ) archtester Gentoo Infrastructure gentoo-dev Security 2013-05-29 15:41:42 UTC
fully fixed in both sys-auth/keystone-2012.2.4-r4 and dev-python/keystoneclient-0.2.4
Comment 3 Chris Reffett (RETIRED) gentoo-dev Security 2013-07-02 21:39:08 UTC
It's been fixed, no vulnerable ebuilds in tree. Closing noglsa.
