## Description

The x86-64 kernel system-call functionality in Xen 4.1.2 and earlier, as
used in Citrix XenServer 6.0.2 and earlier and other products; Oracle
Solaris 11 and earlier; illumos before r13724; Joyent SmartOS before
20120614T184600Z; FreeBSD before 9.0-RELEASE-p3; NetBSD 6.0 Beta and
earlier; Microsoft Windows Server 2008 R2 and R2 SP1 and Windows 7 Gold and
SP1; and possibly other operating systems, when running on an Intel
processor, incorrectly uses the sysret path in cases where a certain
address is not a canonical address, which allows local users to gain
privileges via a crafted application. NOTE: because this issue is due to
incorrect use of the Intel specification, it should have been split into
separate identifiers; however, there was some value in preserving the
original mapping of the multi-codebase coordinated-disclosure effort to a
single identifier.
