The Ubuntu Security Notice USN-1823-1 highlights vulnerabilities in the kernel that could lead to privilege escalation and information disclosure.
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:

Matthias Weckbecker discovered that, when using the OpenStack API to

setup libvirt-based hypervisors, an authenticated user could inject

files in arbitrary locations on the file system of the host running

Nova. A remote attacker could use this to gain root privileges. This

issue only affects Ubuntu 12.04 LTS. (CVE-2012-3360)

Pádraig Brady discovered that an authenticated user could corrupt

arbitrary files of the host running Nova. A remote attacker could

use this to cause a denial of service or possibly gain privileges.
