Our reader Marc reports a vulnerability posted by Cisco yesterday:

This issue affects hosts that support and are running Guests as a Hypervisor.  In particular, the note calls out model 800 Industrial ISR Routers and model 1000 Grid routers.  The vulnerability describes a failure in RBAC (Role Based Access Control), where a guest user can get access to a guest VM when only admin users have that access configured - so a privilege escallation from host to guest.

While this affects only a very small subset of Cisco customers, the customers that are affected are likely to be in the public utility sector, and be subject to NERC / FERC regulatory controls.  

So for the folks that are affected by this, please treat this as a high priority, time to schedule a maintenance window to patch!
