Summary: 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. per: http://technet.microsoft.com/en-us/security/bulletin/ms12-042
