The outs instruction emulation in Xen 3.1.x, 4.2.x, 4.3.x, and earlier,
when using FS: or GS: segment override, uses an uninitialized variable as a
segment base, which allows local 64-bit PV guests to obtain sensitive
information (hypervisor stack content) via unspecified vectors related to
stale data in a segment register.
