The Ubuntu Security Notice USN-1546-1 tackles a critical OpenStack vulnerability posing a risk of unauthorized access on server instances.
Nova could be made to overwrite or corrupt arbitrary files in the compute host file system.

Summary

Nova could be made to overwrite or corrupt arbitrary files in the compute

host file system.

Software Description:

- nova: OpenStack Compute cloud infrastructure

Details:

Padraig Brady discovered that the fix for CVE-2012-3361 was incomplete and

an authenticated user could still corrupt arbitrary files on the host

running Nova. A remote attacker could use this to cause a denial of service

or possibly gain privileges.

Update Instructions

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
  python-nova                     2012.1+stable~20120612-3ee026e-0ubuntu1.3

Ubuntu 11.10:
  python-nova                     2011.3-0ubuntu6.10

In general, a standard system update will make all the necessary changes.
