An issue was discovered in Xen through 4.9.x. Grant copying code made an implication that any grant pin would be accompanied by a suitable page reference. Other portions of code, however, did not match up with that assumption. When such a grant copy operation is being done on a grant of a dying domain, the assumption turns out wrong. A malicious guest administrator can cause hypervisor memory corruption, most likely resulting in host crash and a Denial of Service. • http://www.openwall.com/lists/oss-security/2017/10/24/3 http://www.securityfocus.com/bid/101564 http://www.securitytracker.com/id/1039653 http://xenbits.xen.org/xsa/advisory-236.html https://lists.debian.org/debian-lts-announce/2018/10/msg00009.html https://support.citrix.com/article/CTX229057 https://www.debian.org/security/2017/dsa-4050 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

An issue was discovered in Xen 4.4.x through 4.9.x allowing ARM guest OS users to cause a denial of service (prevent physical CPU usage) because of lock mishandling upon detection of an add-to-physmap error. Se ha descubierto un problema en Xen desde las versiones 4.4.x hasta las versiones 4.9.x que permite que usuarios invitados del sistema operativo ARM provoquen una denegación de servicio (imposibilidad de emplear los recursos físicos de la CPU) debido a la gestión incorrecta de los bloqueos al detectarse un error add-to-physmap. • http://www.debian.org/security/2017/dsa-3969 http://www.securitytracker.com/id/1039568 https://xenbits.xen.org/xsa/advisory-235.html • CWE-400: Uncontrolled Resource Consumption •

An issue was discovered in Xen through 4.9.x allowing x86 HVM guest OS users to obtain sensitive information from the host OS (or an arbitrary guest OS) because intercepted I/O operations can cause a write of data from uninitialized hypervisor stack memory. Se ha descubierto un problema en Xen hasta las versiones 4.9.x que permite que usuarios invitados del sistema operativo x86 HMV obtengan información sensible del sistema operativo host (o un sistema operativo invitado arbitrario) debido a que las operaciones I/O interceptadas pueden provocar la escritura de datos de la memoria de pila del hipervisor no inicializado. • http://www.securityfocus.com/bid/101496 http://www.securitytracker.com/id/1039568 https://lists.debian.org/debian-lts-announce/2017/11/msg00027.html https://lists.debian.org/debian-lts-announce/2018/10/msg00009.html https://security.gentoo.org/glsa/201801-14 https://support.citrix.com/article/CTX228867 https://www.debian.org/security/2017/dsa-4050 https://xenbits.xen.org/xsa/advisory-239.html • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

An issue was discovered in Xen through 4.9.x allowing x86 guest OS users to cause a denial of service (hypervisor crash) or possibly gain privileges because MSI mapping was mishandled. Se ha descubierto un problema en Xen hasta las versiones 4.9.x que permite que usuarios invitados del sistema operativo x86 provoquen una denegación de servicio (cierre inesperado del hipervisor) o que puedan obtener privilegios debido a que se gestionó de manera incorrecta la asignación MSI. • http://www.securityfocus.com/bid/101500 http://www.securitytracker.com/id/1039568 https://lists.debian.org/debian-lts-announce/2018/10/msg00009.html https://security.gentoo.org/glsa/201801-14 https://support.citrix.com/article/CTX228867 https://www.debian.org/security/2017/dsa-4050 https://xenbits.xen.org/xsa/advisory-237.html •
