Ubuntu Security Notice (C) 2013-2016 Canonical, Inc. / NASL script (C) 2013-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing a security-related patch.
Loganathan Parthipan discovered that Nova did not properly validate
VNC tokens after an instance was deleted. An authenticated attacker
could exploit this to access other virtual machines under certain
circumstances. This issue did not affect Ubuntu 11.10. (CVE-2013-0335)
Vish Ishaya discovered that Nova did not always enforce quotas on
fixed IPs. An authenticated attacker could exploit this to cause a
denial of service via resource consumption. Nova will now enforce a
quota limit of 10 fixed IPs per instance, which is configurable via
'quota_fixed_ips' in /etc/nova/nova.conf. (CVE-2013-1838).
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.
Update the affected python-nova package.
