As explain in http://www.mulix.org/pubs/misc/sriovsec-tr.pdf an attacker that has been assigned a VF of a NIC for its VM can block the network access for all the VMs using a VF of the same card by sending control flow PAUSE commands at the right interval.
The attack is described as hard to detect, easy to implement and absolutely efficient (throughput drops to 0).
A VF of a SR-IOV virtualized NIC can be assigned via pci aliases or with neutron ports.
I suppose with a VF assigned via a nova pci-passthrough these PAUSE commands would block the network. Would it be the case as well using the neutron port method ?
I don't have enough knowledge on neutron's functioning to see if these threats are serious or not, and I do not have the set up to test this myself. |
This issue is being treated as a potential security risk under embargo. Please do not make any public mention of embargoed (private) security vulnerabilities before their coordinated publication by the OpenStack Vulnerability Management Team in the form of an official OpenStack Security Advisory. This includes discussion of the bug or associated fixes in public forums such as mailing lists, code review systems and bug trackers. Please also avoid private disclosure to other individuals not already approved for access to this information, and provide this same reminder to those who are made aware of the issue prior to publication. All discussion should remain confined to this private bug report, and any proposed fixes should be added to the bug as attachments.
