This feature was added: - Added script, udev rule and systemd service to watch for vcpu online/offline events in a HVM domU. They are triggered via 'xl vcpu-set domU N' 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-2018-7540: x86 PV guest OS users were able to cause a denial of service (host OS CPU hang) via non-preemptable L3/L4 pagetable freeing (bsc#1080635). - CVE-2018-7541: Guest OS users were able to cause a denial of service (hypervisor crash) or gain privileges by triggering a grant-table transition from v2 to v1 (bsc#1080662). - CVE-2018-7542: x86 PVH guest OS users were able to cause a denial of service (NULL pointer dereference and hypervisor crash) by leveraging the mishandling of configurations that lack a Local APIC (bsc#1080634). These non-security issues were fixed: - bsc#1087252: Update built-in defaults for xenstored in stubdom, keep default to run xenstored as daemon in dom0 - bsc#1087251: Preserve xen-syms from xen-dbg.gz to allow processing vmcores with crash(1) - bsc#1072834: Prevent unchecked MSR access error This update was imported from the SUSE:SLE-12-SP3:Update update project.</description> <summary>Security update for xen</summary> </patchinfo>
