*** This bug is a security vulnerability ***
Public security bug reported:
RHSA-2011:1065 introduced a regression in the Ethernet bridge
implementation. If a system had an interface in a bridge, and an
attacker on the local network could send packets to that interface, they
could cause a denial of service on that system. Xen hypervisor and KVM
(Kernel-based Virtual Machine) hosts often deploy bridge interfaces
