An update that solves four vulnerabilities and has 7 fixes
is now available.

Description:

This update for xen fixes several issues.

These security issues were fixed:

- CVE-2018-8897: Prevent mishandling of debug exceptions on x86 (XSA-260,
bsc#1090820)
- Handle HPET timers in IO-APIC mode correctly to prevent malicious or
buggy HVM guests from causing a hypervisor crash or potentially
privilege escalation/information leaks (XSA-261, bsc#1090822)
- Prevent unbounded loop, induced by qemu allowing an attacker to
permanently keep a physical CPU core busy (XSA-262, bsc#1090823)
- CVE-2018-10472: x86 HVM guest OS users (in certain configurations) were
able 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 (bsc#1089152).
- CVE-2018-10471: x86 PV guest OS users were able 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 CVE-2017-5754
(bsc#1089635).
- CVE-2018-7550: The load_multiboot function allowed local guest OS users
to execute arbitrary code on the host via a mh_load_end_addr value
greater than mh_bss_end_addr, which triggers an out-of-bounds read or
write memory access (bsc#1083292).

These non-security issues were fixed:

- bsc#1072834: Prevent unchecked MSR access error
- bsc#1035442: Increase the value of LIBXL_DESTROY_TIMEOUT from 10 to 100
seconds, allowing for more domUs to be shutdown in parallel
- bsc#1057493: Prevent DomU crash
