SUSE-SU-2017:1715-1 Security update for xen

This update for xen fixes the following security issues: - blkif responses leaked backend stack data, which allowed unprivileged guest to obtain sensitive information from the host or other guests XSA-216, bsc1042863 - Page transfer might have allowed PV guest to elevate privilege XSA-217,...

UBUNTU-CVE-2017-7518

A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap flagTF bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exceptionDB being raised in the guest stack. A user/process inside a guest could use this flaw to...

x86: insufficient reference counts during shadow emulation

ISSUE DESCRIPTION When using shadow paging, writes to guest pagetables must be trapped and emulated, so the shadows can be suitably adjusted as well. When emulating the write, Xen maps the guests pagetables to make the final adjustment and leave the guest's view of its state consistent. However,...
