Exceptions to this are\n- when a memory operand lives in (emulated or passed through) memory mapped IO space,\n- in the case of guests running in 32-bit PAE mode, when such an instruction is (in execution flow) within four instructions of one doing a page table update,\n- when an Invalid Opcode exception gets raised by a guest instruction, and the guest then (likely maliciously) alters the instruction to become one of the affected ones,\n- when the guest is in real mode (in which case there are no privilege checks anyway).\n#### IMPACT\nMalicious HVM guest user mode code may be able to elevate its privileges to guest supervisor mode, or to crash the guest.\n#### VULNERABLE SYSTEMS\nXen 3.2.1 and onward are vulnerable on x86 systems.\nARM systems are not vulnerable.\nOnly user processes in x86 HVM guests can take advantage of this vulnerability.\n", "published": "2014-11-18T12:00:00", "cvss": {"score": 1.9, "vector": "AV:LOCAL/AC:MEDIUM/Au:NONE/C:NONE/I:NONE/A:PARTIAL/"}, "href": "http://xenbits.xen.org/xsa/advisory-110.html", "cvelist": ["CVE-2014-8595"], "lastseen": "2016-09-04T11:24:07"}], "nessus": [{"id": "ORACLEVM_OVMSA-2015-0096.NASL", "type": "nessus", "title": "OracleVM 3.2 : xen (OVMSA-2015-0096)", "description": "The remote OracleVM system is missing necessary patches to address critical security updates : please see Oracle VM Security Advisory OVMSA-2015-0096 for details.", "published": "2015-07-28T00:00:00", "cvss": {"score": 7.2, "vector": "AV:LOCAL/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}, "href": "https://www.tenable.com/plugins/index.php?view=single&id=85038", "cvelist": ["CVE-2014-8595", "CVE-2015-5154", "CVE-2015-2152"], "lastseen": "2017-02-17T01:02:55"}, {"id": "DEBIAN_DSA-3140.NASL", "type": "nessus", "title": "Debian DSA-3140-1 : xen - security update", "description": "Multiple security issues have been discovered in the Xen virtualisation solution which may result in denial of service, information disclosure or privilege escalation.\n\n - CVE-2014-8594 Roger Pau Monne and Jan Beulich discovered that incomplete restrictions on MMU update hypercalls may result in privilege escalation.\n\n - CVE-2014-8595 Jan Beulich discovered that missing privilege level checks in the x86 emulation of far branches may result in privilege escalation.\n\n - CVE-2014-8866 Jan Beulich discovered that an error in compatibility mode hypercall argument translation may result in denial of service.\n\n - CVE-2014-8867 Jan Beulich discovered that an insufficient restriction in acceleration support for the 'REP MOVS' instruction may result in denial of service.\n\n - CVE-2014-9030 Andrew Cooper discovered a page reference leak in MMU_MACHPHYS_UPDATE handling, resulting in denial of service.", "published": "2015-01-28T00:00:00", "cvss": {"score": 7.1, "vector": "AV:NETWORK/AC:MEDIUM/Au:NONE/C:NONE/I:NONE/A:COMPLETE/"}, "href": "https://www.tenable.com/plugins/index.php?view=single&id=81027", "cvelist": ["CVE-2014-8866", "CVE-2014-8595", "CVE-2014-8867", "CVE-2014-8594", "CVE-2014-9030"], "lastseen": "2016-09-26T17:26:40"}, {"id": "CITRIX_XENSERVER_CTX200288.NASL", "type": "nessus", "title": "Citrix XenServer Multiple Vulnerabilities (CTX200288)", "description": "The remote host is running a version of Citrix XenServer that is affected by multiple vulnerabilities :\n\n - A local privilege escalation vulnerability exists due to improperly restricted access to 'PHYSDEVOP_{prepare,release}_msix' operations by unprivileged guests.
