Red Hat Security Advisory 2011-1019-01 - The libvirt library is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. An integer overflow flaw was found in libvirtd's RPC call handling. An attacker able to establish read-only connections to libvirtd could trigger this flaw by calling virDomainGetVcpus() with specially-crafted parameters, causing libvirtd to crash.
