Description

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.

Solution(s)

  • gentoo-linux-upgrade-app-emulation-xen
  • gentoo-linux-upgrade-app-emulation-xen-pvgrub
  • gentoo-linux-upgrade-app-emulation-xen-tools

With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
