Summary

Security update for xen

Details

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 loadmultiboot function allowed local guest OS users to execute arbitrary code on the host via a mhloadendaddr value greater than mhbssend_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 LIBXLDESTROYTIMEOUT from 10 to 100 seconds, allowing for more domUs to be shutdown in parallel
bsc#1057493: Prevent DomU crash
