Descriptions

Xen 3.1 through 4.x, when running 64-bit hosts on Intel CPUs, does not clear the NT flag when using an IRET after a SYSENTER instruction, which allows PV guest users to cause a denial of service (hypervisor crash) by triggering a #GP fault, which is not properly handled by another IRET instruction.

Xen 3.1 a la 4.x, cuando ejecuta hosts con arquitectura de 64 bits en CPUs Intel, no limpia la bandera NT cuan emplea una IRET después de una instrucción SYSENTER, lo que permite a usuarios PV provocar una denegación de servicio (caída del hypervisor) provocando un fallo #GP que no está manejado adecuadamente por otra instrucción IRET.

Multiple vulnerabilities have been found in Xen, allowing attackers on a Xen Virtual Machine to execute arbitrary code, cause Denial of Service, or gain access to data on the host. Versions less than 4.2.2-r1 are affected.
