CVE-2012-0217

CVE Details

Release Date:2012-06-12

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; and Microsoft Windows Server 2008 R2 and R2 SP1 and Windows 7 Gold and SP1, 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: this description clearly does not belong in CVE, because a single entry cannot be about independent codebases; however, there was some value in preserving the original mapping of the multi-codebase coordinated-disclosure effort to a single identifier.
