update for xen fixes several issues.\n\nThese security issues were fixed:\n\n- blkif responses leaked backend stack data, which allowed unprivileged guest to obtain sensitive information from the host or other guests (XSA-216, bsc#1042863)\n- Page transfer might have allowed PV guest to elevate privilege (XSA-217, bsc#1042882)\n- Races in the grant table unmap code allowed for informations leaks and potentially privilege escalation (XSA-218, bsc#1042893)\n- Insufficient reference counts during shadow emulation allowed a malicious pair of guest to elevate their privileges to the privileges that XEN runs under (XSA-219, bsc#1042915)\n- Stale P2M mappings due to insufficient error checking allowed malicious guest to leak information or elevate privileges (XSA-222, bsc#1042931)\n- Grant table operations mishandled reference counts allowing malicious guests to escape (XSA-224, bsc#1042938)\n- CVE-2017-9330: USB OHCI Emulation in qemu allowed local guest OS users to cause a denial of service (infinite loop) by leveraging an incorrect return value (bsc#1042160)\n- CVE-2017-8309: Memory leak in the audio/audio.c allowed remote attackers to cause a denial of service (memory consumption) by repeatedly starting and stopping audio capture (bsc#1037243)\n- CVE-2017-8905: Xen a failsafe callback, which might have allowed PV guest OS users to execute arbitrary code on the host OS (XSA-215, bsc#1034845).\n- CVE-2017-9503: The MegaRAID SAS 8708EM2 Host Bus Adapter emulation support was vulnerable to a null pointer dereference issue which allowed a privileged user inside guest to crash the Qemu process on the host resulting in DoS (bsc#1043297)\n- CVE-2017-9374: Missing free of 's->ipacket', causes a host memory leak, allowing for DoS (bsc#1043074)\n- CVE-2017-8112: hw/scsi/vmw_pvscsi.c allowed local guest OS privileged users to cause a denial of service (infinite loop and CPU consumption) via the message ring page count (bsc#1036470)\n- Missing NULL pointer check in event channel poll allows guests to DoS the host (XSA-221, bsc#1042924)\n\t\nThese non-security issues were fixed:\n\n- bsc#1032148: Ensure that time doesn't goes backwards during live migration of HVM domU\n- bsc#1031460: Fixed DomU Live Migration \n- bsc#1014136: Fixed kdump SLES12-SP2\n- bsc#1026236: Equalized paravirtualized vs. fully virtualized migration speed\n","id":"SUSE-SU-2017:1770-1","modified":"2017-07-04T14:04:01Z","published":"2017-07-04T14:04:01Z","references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2017/suse-su-20171770-1/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1014136"},{"type":"REPORT","url":"https://bugzilla.suse.com/1026236"},{"type":"REPORT","url":"https://bugzilla.suse.com/1027519"},{"type":"REPORT","url":"https://bugzilla.suse.com/1031460"},{"type":"REPORT","url":"https://bugzilla.suse.com/1032148"},{"type":"REPORT","url":"https://bugzilla.suse.com/1034845"},{"type":"REPORT","url":"https://bugzilla.suse.com/1036470"},{"type":"REPORT","url":"https://bugzilla.suse.com/1037243"},{"type":"REPORT","url":"https://bugzilla.suse.com/1042160"},{"type":"REPORT","url":"https://bugzilla.suse.com/1042863"},{"type":"REPORT","url":"https://bugzilla.suse.com/1042882"},{"type":"REPORT","url":"https://bugzilla.suse.com/1042893"},{"type":"REPORT","url":"https://bugzilla.suse.com/1042915"},{"type":"REPORT","url":"https://bugzilla.suse.com/1042924"},{"type":"REPORT","url":"https://bugzilla.suse.com/1042931"},{"type":"REPORT","url":"https://bugzilla.suse.com/1042938"},{"type":"REPORT","url":"https://bugzilla.suse.com/1043074"},{"type":"REPORT","url":"https://bugzilla.suse.com/1043297"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-8112"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-8309"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-8905"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-9330"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-9374"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-9503"}],"related":["CVE-2017-8112","CVE-2017-8309","CVE-2017-8905","CVE-2017-9330","CVE-2017-9374","CVE-2017-9503"],"summary":"Security
