  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. (CVE-2011-2511)

  This update fixes the following bugs:

  * libvirt was rebased from version 0.6.3 to version 0.8.2 in Red Hat
  Enterprise Linux 5.6. A code audit found a minor API change that effected
  error messages seen by libvirt 0.8.2 clients talking to libvirt 0.7.1
  0.7.7 (0.7.x) servers. A libvirt 0.7.x server could send
  VIR_ERR_BUILD_FIREWALL errors where a libvirt 0.8.2 client expected
  VIR_ERR_CONFIG_UNSUPPORTED errors. In other circumstances, a libvirt 0.8.2
  client saw a 'Timed out during operation' message where it should see an
  'Invalid network filter' error. This update adds a backported patch that
  allows libvirt 0.8.2 clients to interoperate with the API as used by
  libvirt 0.7.x servers, ensuring correct error messages are sent.
  (BZ#665075)

  * libvirt could crash if the maximum number of open file descriptors
  (_SC_OPEN_MAX) grew larger than the FD_SETSIZE value because it accessed
  file descriptors outside the bounds of the set. With this update the
  maximum number of open file descriptors can no longer grow larger than the
  FD_SETSIZE value. (BZ#665549)

  * A libvirt race condition was found. An array in the libvirt event
  handlers was accessed with a lock temporarily released. In rare cases, if
  one thread attempted to access this array but a second thread reallocated
  the array before the first thread reacquired a lock, it could lead to the
  first thread attempting to access freed memory, potentially causing libvirt
  to crash. With this update libvirt no longer refers to the old array and,
  consequently, behaves as expected. (BZ#671569)

  * Guests connected to a passthrough NIC would kernel panic if a
  system_reset signal was sent through the QEMU monitor. With this update you
  can reset such guests as expected. (BZ#689880)

  * When using the Xen kernel, the rpmbuild command failed on the xencapstest
  test. With this update you can run rpmbuild successfully when using the Xen
  kernel. (BZ#690459)

  * When a disk was hot unplugged, 'ret >= 0' was passed to the qemuAuditDisk
  calls in disk hotunplug operations before ret was, in fact, set to 0. As
  well, the error path jumped to the 'cleanup&q ...
