Information leak through outs instruction emulation

ISSUE DESCRIPTION The emulation of the outs instruction for 64-bit PV guests uses an uninitialized variable as the segment base for the source data if an FS: or GS: segment override is used, and if the segment descriptor the respective non-null selector in the corresponding selector register poin...
