CVE-2018-7542 (
  An issue was discovered in Xen 4.8.x through 4.10.x allowing x86 PVH guest
  OS users to cause a denial of service (NULL pointer dereference and
  hypervisor crash) by leveraging the mishandling of configurations that lack
  a Local APIC.

CVE-2018-7541 (
  An issue was discovered in Xen through 4.10.x allowing guest OS users to
  cause a denial of service (hypervisor crash) or gain privileges by
  triggering a grant-table transition from v2 to v1.

CVE-2018-7540 (
  An issue was discovered in Xen through 4.10.x allowing x86 PV guest OS users
  to cause a denial of service (host OS CPU hang) via non-preemptable L3/L4
  pagetable freeing.

CVE-2018-5244 (
  In Xen 4.10, new infrastructure was introduced as part of an overhaul to how
  MSR emulation happens for guests. Unfortunately, one tracking structure
  isn't freed when a vcpu is destroyed. This allows guest OS administrators to
  cause a denial of service (host OS memory consumption) by rebooting many

CVE-2018-10472 (
  An issue was discovered in Xen through 4.10.x allowing x86 HVM guest OS
  users (in certain configurations) to read arbitrary dom0 files via QMP live
  insertion of a CDROM, in conjunction with specifying the target file as the
  backing file of a snapshot.

CVE-2018-10471 (
  An issue was discovered in Xen through 4.10.x allowing x86 PV guest OS users
  to cause a denial of service (out-of-bounds zero write and hypervisor crash)
  via unexpected INT 80 processing, because of an incorrect fix for

Comment 3 Tomáš Mózes 2018-08-01 12:12:22 UTC
Please let's merge and stabilize 4.10.1-r1, it fixes multiple CVEs.
Comment 4 Tomáš Mózes 2018-08-20 09:07:10 UTC
Please call stabilization of 4.10.1-r1.
Comment 5 Tomáš Mózes 2018-09-10 06:31:41 UTC
Version 4.10.1-r2 covers all xsa fixes in the stable tree until now, so it's the preferred candidate for stabilization.
Comment 6 Thomas Deutschmann (RETIRED) gentoo-dev 2018-09-10 09:51:33 UTC
Tomáš Mózes is working on an updated 4.11.x package.

@ maintainer(s): Waiting for your ack to start stabilization. We will proceed with pkg list (i.e. stabilization of 4.10.1-r2) on 2018-09-12 if we don't get a reply.
