An issue was discovered in drivers/xen/balloon.c in the Linux kernel before 5.2.3, as used in Xen through 4.12.x, allowing guest OS users to cause a denial of service because of unrestricted resource consumption during the mapping of guest memory, aka CID-6ef36ab967c7. Se detectó un problema en el archivo drivers/xen/balloon.c en el kernel de Linux versiones anteriores a 5.2.3, como es usado en Xen versiones hasta 4.12.x, permitiendo a usuarios del sistema operativo invitado causar una denegación de servicio debido al consumo de recursos sin restricciones durante la asignación de la memoria de invitado , también se conoce como CID-6ef36ab967c7. • http://www.openwall.com/lists/oss-security/2019/10/25/9 http://xenbits.xen.org/xsa/advisory-300.html https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.2.3 https://github.com/torvalds/linux/commit/6ef36ab967c71690ebe7e5ef997a8be4da3bc844 https://security.netapp.com/advisory/ntap-20191031-0005 https://usn.ubuntu.com/4286-1 https://usn.ubuntu.com/4286-2 https://xenbits.xen.org/xsa/advisory-300.html • CWE-770: Allocation of Resources Without Limits or Throttling •

An issue was discovered in Xen through 4.11.x on AMD x86 platforms, possibly allowing guest OS users to gain host OS privileges because TLB flushes do not always occur after IOMMU mapping changes. Se ha descubierto un problema en Xen hasta las versiones 4.11.x en plataformas AMD x86, que podría permitir que usuarios invitados del sistema operativo obtengan privilegios del host del sistema operativo. Esto se debe a que los vaciados TLB no siempre ocurren tras cambios en el mapeo de IOMMU. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00072.html http://www.securityfocus.com/bid/106182 https://lists.debian.org/debian-lts-announce/2019/10/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UXC6BME7SXJI2ZIATNXCAH7RGPI4UKTT https://support.citrix.com/article/CTX239432 https://www.debian.org/security/2019/dsa-4369 https://xenbits.xen.org/xsa/advisory-275.html • CWE-459: Incomplete Cleanup •

An issue was discovered in Xen through 4.11.x on AMD x86 platforms, possibly allowing guest OS users to gain host OS privileges because small IOMMU mappings are unsafely combined into larger ones. Se ha descubierto un problema en Xen hasta las versiones 4.11.x en plataformas AMD x86, que podría permitir que usuarios invitados del sistema operativo obtengan privilegios del host del sistema operativo. Esto se debe a que los mapeos de IOMMU pequeños se combinan de forma insegura con mapeos más grandes. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00072.html http://www.securityfocus.com/bid/106182 https://lists.debian.org/debian-lts-announce/2019/10/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UXC6BME7SXJI2ZIATNXCAH7RGPI4UKTT https://support.citrix.com/article/CTX239432 https://www.debian.org/security/2019/dsa-4369 https://xenbits.xen.org/xsa/advisory-275.html • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
