User Mode Scheduler Memory Corruption Vulnerability (CVE-2012-0217)

oval:org.mitre.oval:def:15596

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.
