Red Hat Security Advisory 2012-1375-01 - An updated rhev-hypervisor6 package that fixes one security issue and one bug is now available. A flaw was found in the way socket buffers requiring TSO were handled by the sfc driver. If the skb did not fit within the minimum-size of the transmission queue, the network card could repeatedly reset itself. A remote attacker could use this flaw to cause a denial of service.
