An update that solves 6 vulnerabilities and has 9 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#1027519: Missing upstream bug fixes

- bsc#1015348: libvirtd does not start during boot

- bsc#1022555: Timeout in "execution of /etc/xen/scripts/block add
