08 Dec 2018 — 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.

17 Aug 2018 — An issue was discovered in Xen through 4.11.x. The logic in oxenstored for handling writes depended on the order of evaluation of expressions making up a tuple. As indicated in section 7.7.3 "Operations on data structures" of the OCaml manual, the order of evaluation of subexpressions is not specified. In practice, different implementations behave differently. Thus, oxenstored may not enforce the configured quota-maxentity. • http://xenbits.xen.org/xsa/advisory-272.html • CWE-400: Uncontrolled Resource Consumption •
