CVE-2013-1838
|
| Created: | March 21, 2013 |
Updated: | April 5, 2013 |
| Description: |
From the Ubuntu advisory:
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) |
