CVE-2016-9932 |
CMPXCHG8B emulation in Xen 3.3.x through 4.7.x on x86 systems allows local HVM guest OS users to obtain sensitive information from host stack memory via a "supposedly-ignored" operand size prefix. Published: January 26, 2017; 10:59:00 AM -0500 |
V3.0: 3.3 LOW V2.0: 2.1 LOW |
CVE-2016-10025 |
VMFUNC emulation in Xen 4.6.x through 4.8.x on x86 systems using AMD virtualization extensions (aka SVM) allows local HVM guest OS users to cause a denial of service (hypervisor crash) by leveraging a missing NULL pointer check. Published: January 26, 2017; 10:59:00 AM -0500 |
V3.0: 5.5 MEDIUM V2.0: 2.1 LOW |
CVE-2016-10024 |
Xen through 4.8.x allows local x86 PV guest OS kernel administrators to cause a denial of service (host hang or crash) by modifying the instruction stream asynchronously while performing certain kernel operations. Published: January 26, 2017; 10:59:00 AM -0500 |
V3.0: 6.0 MEDIUM V2.0: 4.9 MEDIUM |
CVE-2016-10013 |
Xen through 4.8.x allows local 64-bit x86 HVM guest OS users to gain privileges by leveraging mishandling of SYSCALL singlestep during emulation. Published: January 26, 2017; 10:59:00 AM -0500 |
V3.0: 7.8 HIGH V2.0: 4.6 MEDIUM |
CVE-2016-9385 |
The x86 segment base write emulation functionality in Xen 4.4.x through 4.7.x allows local x86 PV guest OS administrators to cause a denial of service (host crash) by leveraging lack of canonical address checks. Published: January 23, 2017; 4:59:02 PM -0500 |
V3.0: 6.0 MEDIUM V2.0: 4.9 MEDIUM |
CVE-2016-9382 |
Xen 4.0.x through 4.7.x mishandle x86 task switches to VM86 mode, which allows local 32-bit x86 HVM guest OS users to gain privileges or cause a denial of service (guest OS crash) by leveraging a guest operating system that uses hardware task switching and allows a new task to start in VM86 mode. Published: January 23, 2017; 4:59:02 PM -0500 |
V3.0: 7.8 HIGH V2.0: 4.6 MEDIUM |
CVE-2016-7777 |
Xen 4.7.x and earlier does not properly honor CR0.TS and CR0.EM, which allows local x86 HVM guest OS users to read or modify FPU, MMX, or XMM register state information belonging to arbitrary tasks on the guest by modifying an instruction while the hypervisor is preparing to emulate it. Published: October 07, 2016; 10:59:10 AM -0400 |
V3.0: 6.3 MEDIUM V2.0: 3.3 LOW |
CVE-2016-7094 |
Buffer overflow in Xen 4.7.x and earlier allows local x86 HVM guest OS administrators on guests running with shadow paging to cause a denial of service via a pagetable update. Published: September 21, 2016; 10:25:25 AM -0400 |
V3.0: 4.1 MEDIUM V2.0: 1.5 LOW |
CVE-2016-7093 |
Xen 4.5.3, 4.6.3, and 4.7.x allow local HVM guest OS administrators to overwrite hypervisor memory and consequently gain host OS privileges by leveraging mishandling of instruction pointer truncation during emulation. Published: September 21, 2016; 10:25:24 AM -0400 |
V3.0: 8.2 HIGH V2.0: 7.2 HIGH |
CVE-2016-6259 |
Xen 4.5.x through 4.7.x do not implement Supervisor Mode Access Prevention (SMAP) whitelisting in 32-bit exception and event delivery, which allows local 32-bit PV guest OS kernels to cause a denial of service (hypervisor and VM crash) by triggering a safety check. Published: August 02, 2016; 12:59:09 PM -0400 |
V3.0: 6.2 MEDIUM V2.0: 4.9 MEDIUM |
CVE-2016-6258 |
The PV pagetable code in arch/x86/mm.c in Xen 4.7.x and earlier allows local 32-bit PV guest OS administrators to gain host OS privileges by leveraging fast-paths for updating pagetable entries. Published: August 02, 2016; 12:59:08 PM -0400 |
V3.0: 8.8 HIGH V2.0: 7.2 HIGH |
