  "details" : [ "Xen 4.1.x and 4.2.x, when the XSA-45 patch is in place, does not properly maintain references on pages stored for deferred cleanup, which allows local PV guest kernels to cause a denial of service (premature page free and hypervisor crash) or possibly gain privileges via unspecified vectors." ],
  "statement" : "Not vulnerable.\nThis issue did not affect the versions of the kernel-xen package as shipped with Red Hat Enterprise Linux 5 because we did not backport CVE-2013-1918 fix.\nThis issue did not affect Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG 2 because of missing Xen hypervisor support.",
