Ubuntu 12.10 / 13.04 / 13.10 : keystone vulnerability (USN-2034-1)

Ubuntu Security Notice (C) 2013-2016 Canonical, Inc. / NASL script (C) 2013-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Brant Knudson discovered a logic error in the LDAP backend in Keystone
where removing a role on a tenant for a user who does not have that
role would instead add the role to the user. An authenticated user
could use this to gain privileges. Ubuntu is not configured to use the
LDAP Keystone backend by default.

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.

Risk factor :

Low / CVSS Base Score : 3.3
(CVSS2#AV:L/AC:M/Au:N/C:P/I:P/A:N)
CVSS Temporal Score : 2.9
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : false
