[Xen-users] Xen Security Advisory 123 (CVE-2015-2151) - Hypervisor memory corruption due to x86 emulator flaw
http://lists.xen.org/archives/html/xen-users/2015-03/msg00037.html

ISSUE DESCRIPTION
=================
Instructions with register operands ignore eventual segment overrides
encoded for them. Due to an insufficiently conditional assignment such
a bogus segment override can, however, corrupt a pointer used
subsequently to store the result of the instruction.
