Announcement ID: SUSE-SU-2018:1216-1 Rating: important References: #1027519 #1086039 #1089152 #1089635 #1090820 #1090822 #1090823 Cross-References: CVE-2018-10471 CVE-2018-10472 CVE-2018-8897 Affected Products: SUSE OpenStack Cloud 7 SUSE Linux Enterprise Server for SAP 12-SP2 SUSE Linux Enterprise Server 12-SP2-LTSS SUSE Enterprise Storage 4 ______________________________________________________________________________
An update that solves three vulnerabilities and has four 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).
These non-security issues were fixed:
- bsc#1086039: Ensure that Dom0 does represent DomU cpu flags correctly - bsc#1027519: Fixed shadow mode guests
