Ubuntu 12.04 LTS : nova vulnerability (USN-1501-1)

Ubuntu Security Notice (C) 2012-2016 Canonical, Inc. / NASL script (C) 2012-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Dan Prince discovered that the Nova scheduler, when using
DifferentHostFilter or SameHostFilter, would make repeated database
instance lookup calls based on passed scheduler hints. An
authenticated attacker could use this to cause a denial of service.

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 :

Low / CVSS Base Score : 3.5
(CVSS2#AV:N/AC:M/Au:S/C:N/I:N/A:P)
CVSS Temporal Score : 2.9
(CVSS2#E:F/RL:OF/RC:C)
