Additionally memory \n  leaks were also possible (bsc#1126140).\n- Fixed a race condition issue which could allow malicious PV guests to escalate their privilege to that \n  of the hypervisor (bsc#1126141).\n- CVE-2019-9824: Fixed an information leak in SLiRP networking implementation which could allow a user/process \n  to read uninitialised stack memory contents (bsc#1129623).\n- CVE-2018-19967: Fixed HLE constructs that allowed guests to lock up the host,\n  resulting in a Denial of Service (DoS). (XSA-282) (bsc#1114988)\n\nOther issue addressed: \n\n- Added Xen cmdline option 'suse_vtsc_tolerance' to avoid TSC emulation for HVM domUs (bsc#1026236).\n","id":"SUSE-SU-2019:0921-1","modified":"2019-04-10T07:17:50Z","published":"2019-04-10T07:17:50Z","references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2019/suse-su-20190921-1/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1026236"},{"type":"REPORT","url":"https://bugzilla.suse.com/1114988"},{"type":"REPORT","url":"https://bugzilla.suse.com/1123157"},{"type":"REPORT","url":"https://bugzilla.suse.com/1126140"},{"type":"REPORT","url":"https://bugzilla.suse.com/1126141"},{"type":"REPORT","url":"https://bugzilla.suse.com/1126192"},{"type":"REPORT","url":"https://bugzilla.suse.com/1126195"},{"type":"REPORT","url":"https://bugzilla.suse.com/1126196"},{"type":"REPORT","url":"https://bugzilla.suse.com/1126198"},{"type":"REPORT","url":"https://bugzilla.suse.com/1126201"},{"type":"REPORT","url":"https://bugzilla.suse.com/1127400"},{"type":"REPORT","url":"https://bugzilla.suse.com/1129623"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2018-19967"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2019-6778"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2019-9824"}],"related":["CVE-2018-19967","CVE-2019-6778","CVE-2019-9824"],"summary":"Security update for xen","upstream":["CVE-2018-19967","CVE-2019-6778","CVE-2019-9824"]}
