A user inside\n  a guest could have used this flaw to crash the qemu process resulting in a\n  Denial of Service (DoS). (bsc#1111014)\n- CVE-2018-18849: Fixed an out of bounds memory access in the LSI53C895A SCSI\n  host bus adapter emulation, which allowed a user and/or process to crash the\n  qemu process resulting in a Denial of Service (DoS). (bsc#1114423)\n- CVE-2018-18883: Fixed an issue related to inproper restriction of nested\n  VT-x, which allowed a guest to cause Xen to crash, resulting in a Denial of\n  Service (DoS). (XSA-278) (bsc#1114405)\n- CVE-2018-19961, CVE-2018-19962: Fixed an issue related to insufficient TLB\n  flushing with AMD IOMMUs, which potentially allowed a guest to escalate its\n  privileges, may cause a Denial of Service (DoS) affecting the entire host, or\n  may be able to access data it is not supposed to access. (XSA-275)\n  (bsc#1115040)\n- CVE-2018-19963: Fixed the allocation of pages used to communicate with\n  external emulators, which may have cuased Xen to crash, resulting in a Denial\n  of Service (DoS). (XSA-276) (bsc#1115043)\n- CVE-2018-19965: Fixed an issue related to the INVPCID instruction in case\n  non-canonical addresses are accessed, which may allow a guest to cause Xen to\n  crash, resulting in a Denial of Service (DoS) affecting the entire host.\n  (XSA-279) (bsc#1115045)\n- CVE-2018-19966: Fixed an issue related to a previous fix for XSA-240, which\n  conflicted with shadow paging and allowed a guest to cause Xen to crash,\n  resulting in a Denial of Service (DoS) (XSA-280) (bsc#1115047)\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- CVE-2018-19964: Fixed the incorrect error handling of p2m page removals,\n  which allowed a guest to cause a deadlock, resulting in a Denial of Service\n  (DoS) affecting the entire host. (XSA-277) (bsc#1115044)\n- CVE-2018-19665: Fixed an integer overflow resulting in memory corruption in\n  various Bluetooth functions, allowing this to crash qemu process resulting in\n  Denial of Service (DoS). (bsc#1117756).\n\nOther bugs fixed:\n\n- Fixed an issue related to a domU hang on SLE12-SP3 HV (bsc#1108940)\n\n","id":"SUSE-SU-2019:0003-1","modified":"2019-01-02T10:39:50Z","published":"2019-01-02T10:39:50Z","references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2019/suse-su-20190003-1/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1027519"},{"type":"REPORT","url":"https://bugzilla.suse.com/1108940"},{"type":"REPORT","url":"https://bugzilla.suse.com/1111014"},{"type":"REPORT","url":"https://bugzilla.suse.com/1114405"},{"type":"REPORT","url":"https://bugzilla.suse.com/1114423"},{"type":"REPORT","url":"https://bugzilla.suse.com/1114988"},{"type":"REPORT","url":"https://bugzilla.suse.com/1115040"},{"type":"REPORT","url":"https://bugzilla.suse.com/1115043"},{"type":"REPORT","url":"https://bugzilla.suse.com/1115044"},{"type":"REPORT","url":"https://bugzilla.suse.com/1115045"},{"type":"REPORT","url":"https://bugzilla.suse.com/1115047"},{"type":"REPORT","url":"https://bugzilla.suse.com/1117756"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2018-17963"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2018-18849"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2018-18883"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2018-19665"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2018-19961"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2018-19962"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2018-19963"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2018-19964"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2018-19965"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2018-19966"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2018-19967"}],"related":["CVE-2018-17963","CVE-2018-18849","CVE-2018-18883","CVE-2018-19665","CVE-2018-19961","CVE-2018-19962","CVE-2018-19963","CVE-2018-19964","CVE-2018-19965","CVE-2018-19966","CVE-2018-19967"],"summary":"Security update for xen","upstream":["CVE-2018-17963","CVE-2018-18849","CVE-2018-18883","CVE-2018-19665","CVE-2018-19961","CVE-2018-19962","CVE-2018-19963","CVE-2018-19964","CVE-2018-19965","CVE-2018-19966","CVE-2018-19967"]}
