CVE-2014-3608

Status Candidate

Overview

The VMWare driver in OpenStack Compute (Nova) before 2014.1.3 allows remote authenticated users to bypass the quota limit and cause a denial of service (resource consumption) by putting the VM into the rescue state, suspending it, which puts into an ERROR state, and then deleting the image. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-2573.

Ubuntu Security Notice USN-2407-1

Ubuntu Security Notice 2407-1 - Garth Mollett discovered that OpenStack Nova did not properly clean up an instance when using rescue mode with the VMWare driver. A remove authenticated user could exploit this to bypass intended quota limits. By default, Ubuntu does not use the VMWare driver. Amrith Kumar discovered that OpenStack Nova did not properly sanitize log message contents. Under certain circumstances, a local attacker with read access to Nova log files could obtain access to sensitive information. Various other issues were also addressed.

Red Hat Security Advisory 2014-1781-01 - OpenStack Compute launches and schedules large networks of virtual machines, creating a redundant and scalable cloud computing platform. Compute provides the software, control panels, and APIs required to orchestrate a cloud, including running virtual machine instances, managing networks, and controlling access through users and projects. A race condition flaw was found in the way the nova VMware driver handled VNC port allocation. An authenticated user could use this flaw to gain unauthorized console access to instances belonging to other tenants by repeatedly spawning new instances. Note that only nova setups using the VMware driver and the VNC proxy service were affected.
