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.

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.
