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. El modo de usuario Scheduler en el núcleo en Microsoft Windows Server v2008 R2 y R2 SP1 y Windows v7 Gold y SP1 sobre la plataforma x64 no maneja adecuadamente solicitudes del sistema, lo que permite a usuarios locales obtener privilegios a través de una aplicación modificada, también conocida como "vulnerabilidad de corrupción de memoria de modo de usuario Scheduler". It was found that the Xen hypervisor implementation as shipped with Red Hat Enterprise Linux 5 did not properly restrict the syscall return addresses in the sysret return path to canonical addresses. An unprivileged user in a 64-bit para-virtualized guest, that is running on a 64-bit host that has an Intel CPU, could use this flaw to crash the host or, potentially, escalate their privileges, allowing them to execute arbitrary code at the hypervisor level. • https://www.exploit-db.com/exploits/46508 https://www.exploit-db.com/exploits/28718 https://www.exploit-db.com/exploits/20861 http://blog.illumos.org/2012/06/14/illumos-vulnerability-patched http://blog.xen.org/index.php/2012/06/13/the-intel-sysret-privilege-escalation http://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2012-003.txt.asc http://lists.xen.org/archives/html/xen-announce/2012-06/msg00001.html http://lists.xen.org/archives/html/xen-devel/2012-06 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Integer overflow in the xdrmem_getbytes() function, and possibly other functions, of XDR (external data representation) libraries derived from SunRPC, including libnsl, libc, glibc, and dietlibc, allows remote attackers to execute arbitrary code via certain integer values in length fields, a different vulnerability than CVE-2002-0391. Desbordamiento de entero en la función xdrmem_getbytes(), y posiblemente otras funciones, de librerias XDR (representación de datos externos) derivadas de SunRPC, incluyendo libnsl, libc y glibc permite a atacantes remotos ejecutar código arbitrario mediante ciertos valores enteros en campos de longitud. • ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2003-008.txt.asc http://archives.neohapsis.com/archives/vulnwatch/2003-q1/0140.html http://marc.info/?l=bugtraq&m=104810574423662&w=2 http://marc.info/?l=bugtraq&m=104811415301340&w=2 http://marc.info/?l=bugtraq&m=104860855114117&w=2 http://marc.info/?l=bugtraq&m=104878237121402&w=2 http://marc.info/? •
