Ubuntu 14.04 LTS : keystone vulnerabilities (USN-2324-1)

Ubuntu Security Notice (C) 2014-2016 Canonical, Inc. / NASL script (C) 2014-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

Steven Hardy discovered that OpenStack Keystone did not properly
handle chained delegation. A remove authenticated attacker could use
this to gain privileges by creating a new token with additional roles.
(CVE-2014-3476)

Jamie Lennox discovered that OpenStack Keystone did not properly
validate the project id. A remote authenticated attacker may be able
to use this to access other projects. (CVE-2014-3520)

Brant Knudson and Lance Bragstad discovered that OpenStack Keystone
would not always revoke tokens correctly. If Keystone were configured
to use revocation events, a remote authenticated attacker could
continue to have access to resources. (CVE-2014-5251, CVE-2014-5252,
CVE-2014-5253).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected python-keystone package.
