overridden to FS/GS, the result of reading the
overridden segment's descriptor (read_descriptor) is not
checked. If it fails, data_base is left uninitialized.
This can lead to 8 bytes of Xen's stack being leaked to
the guest (implicitly, i.e. via the address given in a
#PF). Coverity-ID: 1055116 This is CVE-2013-4368 /
