  "details" : [ "hw/pci/msix.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access via a crafted address in an msi-x mmio operation.", "An out-of-bounds access flaw was found in the Message Signalled Interrupt (MSI-X) device support of QEMU. This issue occurs while performing MSI-X mmio operations when a guest sent address goes beyond the mmio region. A guest user or process may use this flaw to crash the QEMU process resulting in a denial of service." ],
  "statement" : "In Red Hat OpenStack Platform, because the flaw has a lower impact and the fix would require a substantial amount of development, no update will be provided at this time for the RHOSP qemu-kvm-rhev package.",
  "acknowledgement" : "Red Hat would like to thank Alexander Bulekov, Anatoly Trosinenko, Hanqing Zhao (SSLab Georgia Tech), and Ren Ding (SSLab Georgia Tech) for reporting this issue.",
