|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.|

Vulnerable and fixed packages
The table below lists information on source packages.
|kfreebsd-9 (PTS)||wheezy (security), wheezy||9.0-10+deb70.10||fixed|
|jessie (security), jessie||4.4.1-9+deb8u7||fixed|
The information below is based on the following data on fixed versions.
apparently this code is included in freebsd, xen, as well as
microsoft windows, which is also a part of this id assignment (and a
bit strangely the only os currently called out in the mitre description).
also affected the linux kernel, and was fixed 6 years earlier as CVE-2006-0744.
