Ubuntu 14.04 LTS : nova vulnerability (USN-2325-1)

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 :

Alex Gaynor discovered that OpenStack Nova would sometimes respond
with variable times when comparing authentication tokens. If nova were
configured to proxy metadata requests via Neutron, a remote
authenticated attacker could exploit this to conduct timing attacks
and ascertain configuration details of another instance.

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-nova package.

Risk factor :

Medium / CVSS Base Score : 4.3
(CVSS2#AV:N/AC:M/Au:N/C:P/I:N/A:N)
CVSS Temporal Score : 3.2
(CVSS2#E:U/RL:OF/RC:C)
Public Exploit Available : false
