An update that solves three vulnerabilities and has 5 fixes
is now available.

Description:


This update for xen fixes several issues.

These security issues were fixed:

- A malicious 64-bit PV guest may be able to access all of system memory,
allowing for all of privilege escalation, host crashes, and information
leaks by placing a IRET hypercall in the middle of a multicall batch
(XSA-213, bsc#1034843)
- A malicious pair of guests may be able to access all of system memory,
allowing for all of privilege escalation, host crashes, and information
leaks because of a missing check when transfering pages via
GNTTABOP_transfer (XSA-214, bsc#1034844).
- CVE-2017-7718: hw/display/cirrus_vga_rop.h allowed local guest OS
privileged users to cause a denial of service (out-of-bounds read and
QEMU process crash) via vectors related to copying VGA data via the
cirrus_bitblt_rop_fwd_transp_ and cirrus_bitblt_rop_fwd_ functions
(bsc#1034994).
- CVE-2016-9603: A privileged user within the guest VM could have caused a
heap overflow in the device model process, potentially escalating their
privileges to that of the device model process (bsc#1028655)

These non-security issues were fixed:

- bsc#1029827: Additional xenstore patch
