| CVE-2017-10921 | 1 Xen | 1 Xen | 2019-10-03 | N/A |
| The grant-table feature in Xen through 4.8.x does not ensure sufficient type counts for a GNTMAP_device_map and GNTMAP_host_map mapping, which allows guest OS users to cause a denial of service (count mismanagement and memory corruption) or obtain privileged host OS access, aka XSA-224 bug 2. | ||||
| CVE-2017-12134 | 2 Citrix, Xen | 2 Xenserver, Xen | 2019-10-03 | N/A |
| The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation. | ||||
| CVE-2017-12137 | 3 Citrix, Debian, Xen | 3 Xenserver, Debian Linux, Xen | 2019-10-03 | N/A |
| arch/x86/mm.c in Xen allows local PV guest OS users to gain host OS privileges via vectors related to map_grant_ref. | ||||
| CVE-2017-14319 | 1 Xen | 1 Xen | 2019-10-03 | N/A |
| A grant unmapping issue was discovered in Xen through 4.9.x. When removing or replacing a grant mapping, the x86 PV specific path needs to make sure page table entries remain in sync with other accounting done. Although the identity of the page frame was validated correctly, neither the presence of the mapping nor page writability were taken into account. | ||||
| CVE-2017-14431 | 1 Xen | 1 Xen | 2019-10-03 | N/A |
| Memory leak in Xen 3.3 through 4.8.x allows guest OS users to cause a denial of service (ARM or x86 AMD host OS memory consumption) by continually rebooting, because certain cleanup is skipped if no pass-through device was ever assigned, aka XSA-207. | ||||
| CVE-2017-15590 | 1 Xen | 1 Xen | 2019-10-03 | N/A |
| An issue was discovered in Xen through 4.9.x allowing x86 guest OS users to cause a denial of service (hypervisor crash) or possibly gain privileges because MSI mapping was mishandled. | ||||
| CVE-2017-15592 | 1 Xen | 1 Xen | 2019-10-03 | N/A |
| An issue was discovered in Xen through 4.9.x allowing x86 HVM guest OS users to cause a denial of service (hypervisor crash) or possibly gain privileges because self-linear shadow mappings are mishandled for translated guests. | ||||
| CVE-2017-15593 | 1 Xen | 1 Xen | 2019-10-03 | N/A |
| An issue was discovered in Xen through 4.9.x allowing x86 PV guest OS users to cause a denial of service (memory leak) because reference counts are mishandled. | ||||
| CVE-2017-15594 | 1 Xen | 1 Xen | 2019-10-03 | N/A |
| An issue was discovered in Xen through 4.9.x allowing x86 SVM PV guest OS users to cause a denial of service (hypervisor crash) or gain privileges because IDT settings are mishandled during CPU hotplugging. | ||||
| CVE-2017-15597 | 1 Xen | 1 Xen | 2019-10-03 | N/A |
| An issue was discovered in Xen through 4.9.x. Grant copying code made an implication that any grant pin would be accompanied by a suitable page reference. Other portions of code, however, did not match up with that assumption. When such a grant copy operation is being done on a grant of a dying domain, the assumption turns out wrong. A malicious guest administrator can cause hypervisor memory corruption, most likely resulting in host crash and a Denial of Service. Privilege escalation and information leaks cannot be ruled out. | ||||
| CVE-2017-17044 | 1 Xen | 1 Xen | 2019-10-03 | N/A |
| An issue was discovered in Xen through 4.9.x allowing HVM guest OS users to cause a denial of service (infinite loop and host OS hang) by leveraging the mishandling of Populate on Demand (PoD) errors. | ||||
| CVE-2017-17045 | 1 Xen | 1 Xen | 2019-10-03 | N/A |
| An issue was discovered in Xen through 4.9.x allowing HVM guest OS users to gain privileges on the host OS, obtain sensitive information, or cause a denial of service (BUG and host OS crash) by leveraging the mishandling of Populate on Demand (PoD) Physical-to-Machine (P2M) errors. | ||||
| CVE-2017-17566 | 1 Xen | 1 Xen | 2019-10-03 | N/A |
| An issue was discovered in Xen through 4.9.x allowing PV guest OS users to cause a denial of service (host OS crash) or gain host OS privileges in shadow mode by mapping a certain auxiliary page. | ||||
| CVE-2017-7228 | 1 Xen | 1 Xen | 2019-10-03 | N/A |
| An issue (known as XSA-212) was discovered in Xen, with fixes available for 4.8.x, 4.7.x, 4.6.x, 4.5.x, and 4.4.x. The earlier XSA-29 fix introduced an insufficient check on XENMEM_exchange input, allowing the caller to drive hypervisor memory accesses outside of the guest provided input/output arrays. | ||||
| CVE-2017-8903 | 1 Xen | 1 Xen | 2019-10-03 | N/A |
| Xen through 4.8.x on 64-bit platforms mishandles page tables after an IRET hypercall, which might allow PV guest OS users to execute arbitrary code on the host OS, aka XSA-213. | ||||
| CVE-2017-8904 | 1 Xen | 1 Xen | 2019-10-03 | N/A |
| Xen through 4.8.x mishandles the "contains segment descriptors" property during GNTTABOP_transfer (aka guest transfer) operations, which might allow PV guest OS users to execute arbitrary code on the host OS, aka XSA-214. | ||||
| CVE-2017-8905 | 1 Xen | 1 Xen | 2019-10-03 | N/A |
| Xen through 4.6.x on 64-bit platforms mishandles a failsafe callback, which might allow PV guest OS users to execute arbitrary code on the host OS, aka XSA-215. | ||||
| CVE-2018-10981 | 2 Debian, Xen | 2 Debian Linux, Xen | 2019-10-03 | N/A |
| An issue was discovered in Xen through 4.10.x allowing x86 HVM guest OS users to cause a denial of service (host OS infinite loop) in situations where a QEMU device model attempts to make invalid transitions between states of a request. | ||||
| CVE-2018-10982 | 2 Debian, Xen | 2 Debian Linux, Xen | 2019-10-03 | N/A |
| An issue was discovered in Xen through 4.10.x allowing x86 HVM guest OS users to cause a denial of service (unexpectedly high interrupt number, array overrun, and hypervisor crash) or possibly gain hypervisor privileges by setting up an HPET timer to deliver interrupts in IO-APIC mode, aka vHPET interrupt injection. | ||||
| CVE-2018-12891 | 2 Debian, Xen | 2 Debian Linux, Xen | 2019-10-03 | N/A |
| An issue was discovered in Xen through 4.10.x. Certain PV MMU operations may take a long time to process. For that reason Xen explicitly checks for the need to preempt the current vCPU at certain points. A few rarely taken code paths did bypass such checks. By suitably enforcing the conditions through its own page table contents, a malicious guest may cause such bypasses to be used for an unbounded number of iterations. A malicious or buggy PV guest may cause a Denial of Service (DoS) affecting the entire host. Specifically, it may prevent use of a physical CPU for an indeterminate period of time. All Xen versions from 3.4 onwards are vulnerable. Xen versions 3.3 and earlier are vulnerable to an even wider class of attacks, due to them lacking preemption checks altogether in the affected code paths. Only x86 systems are affected. ARM systems are not affected. Only multi-vCPU x86 PV guests can leverage the vulnerability. x86 HVM or PVH guests as well as x86 single-vCPU PV ones cannot leverage the vulnerability. | ||||
