OSSA-2014-035: Nova VMware driver may connect VNC to another tenant’s console¶
October 14, 2014
Nova: up to 2014.1.3
Marcio Roberto Starke reported a vulnerability in the Nova VMware driver. A race condition in its VNC port allocation may cause it to connect the wrong console if instances are created concurrently. By repeatedly spawning new instances, an authenticated user may be able to gain unauthorized console access to instances belonging to other tenants. Only Nova setups using the VMware driver and the VNC proxy service are affected.
