| CVE-2017-8904 | 1 Xen | 1 Xen | 2024-11-21 | 6.8 MEDIUM | 8.8 HIGH |
| 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-2017-8903 | 1 Xen | 1 Xen | 2024-11-21 | 7.2 HIGH | 8.8 HIGH |
| 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-2017-7995 | 3 Novell, Suse, Xen | 6 Suse Linux Enterprise Point Of Sale, Suse Linux Enterprise Server, Manager and 3 more | 2024-11-21 | 1.7 LOW | 3.8 LOW |
| Xen PV guest before Xen 4.3 checked access permissions to MMIO ranges only after accessing them, allowing host PCI device space memory reads, leading to information disclosure. This is an error in the get_user function. NOTE: the upstream Xen Project considers versions before 4.5.x to be EOL. | |||||
| CVE-2017-7228 | 1 Xen | 1 Xen | 2024-11-21 | 7.2 HIGH | 8.2 HIGH |
| 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-2017-2620 | 5 Citrix, Debian, Qemu and 2 more | 10 Xenserver, Debian Linux, Qemu and 7 more | 2024-11-21 | 9.0 HIGH | 5.5 MEDIUM |
| Quick emulator (QEMU) before 2.8 built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The issue could occur while copying VGA data in cirrus_bitblt_cputovideo. A privileged user inside guest could use this flaw to crash the QEMU process OR potentially execute arbitrary code on host with privileges of the QEMU process. | |||||
| CVE-2017-2615 | 5 Citrix, Debian, Qemu and 2 more | 10 Xenserver, Debian Linux, Qemu and 7 more | 2024-11-21 | 9.0 HIGH | 5.5 MEDIUM |
| Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator support is vulnerable to an out-of-bounds access issue. It could occur while copying VGA data via bitblt copy in backward mode. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS or potentially execute arbitrary code on the host with privileges of QEMU process on the host. | |||||
| CVE-2017-17566 | 1 Xen | 1 Xen | 2024-11-21 | 6.9 MEDIUM | 7.8 HIGH |
| 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-2017-17565 | 1 Xen | 1 Xen | 2024-11-21 | 4.7 MEDIUM | 5.6 MEDIUM |
| An issue was discovered in Xen through 4.9.x allowing PV guest OS users to cause a denial of service (host OS crash) if shadow mode and log-dirty mode are in place, because of an incorrect assertion related to M2P. | |||||
| CVE-2017-17564 | 1 Xen | 1 Xen | 2024-11-21 | 6.9 MEDIUM | 7.8 HIGH |
| An issue was discovered in Xen through 4.9.x allowing guest OS users to cause a denial of service (host OS crash) or gain host OS privileges by leveraging incorrect error handling for reference counting in shadow mode. | |||||
| CVE-2017-17563 | 1 Xen | 1 Xen | 2024-11-21 | 6.9 MEDIUM | 7.8 HIGH |
| An issue was discovered in Xen through 4.9.x allowing guest OS users to cause a denial of service (host OS crash) or gain host OS privileges by leveraging an incorrect mask for reference-count overflow checking in shadow mode. | |||||
| CVE-2017-17046 | 1 Xen | 1 Xen | 2024-11-21 | 2.1 LOW | 6.5 MEDIUM |
| An issue was discovered in Xen through 4.9.x on the ARM platform allowing guest OS users to obtain sensitive information from DRAM after a reboot, because disjoint blocks, and physical addresses that do not start at zero, are mishandled. | |||||
| CVE-2017-17045 | 1 Xen | 1 Xen | 2024-11-21 | 7.2 HIGH | 8.8 HIGH |
| 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-2017-17044 | 1 Xen | 1 Xen | 2024-11-21 | 4.9 MEDIUM | 6.5 MEDIUM |
| 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-2017-15597 | 1 Xen | 1 Xen | 2024-11-21 | 9.0 HIGH | 9.1 CRITICAL |
| 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-2017-15596 | 1 Xen | 1 Xen | 2024-11-21 | 4.9 MEDIUM | 6.0 MEDIUM |
| An issue was discovered in Xen 4.4.x through 4.9.x allowing ARM guest OS users to cause a denial of service (prevent physical CPU usage) because of lock mishandling upon detection of an add-to-physmap error. | |||||
| CVE-2017-15595 | 1 Xen | 1 Xen | 2024-11-21 | 7.2 HIGH | 8.8 HIGH |
| An issue was discovered in Xen through 4.9.x allowing x86 PV guest OS users to cause a denial of service (unbounded recursion, stack consumption, and hypervisor crash) or possibly gain privileges via crafted page-table stacking. | |||||
| CVE-2017-15594 | 1 Xen | 1 Xen | 2024-11-21 | 4.6 MEDIUM | 8.8 HIGH |
| 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-2017-15593 | 1 Xen | 1 Xen | 2024-11-21 | 4.9 MEDIUM | 6.5 MEDIUM |
| 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-2017-15592 | 1 Xen | 1 Xen | 2024-11-21 | 7.2 HIGH | 8.8 HIGH |
| 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-2017-15591 | 1 Xen | 1 Xen | 2024-11-21 | 4.9 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Xen 4.5.x through 4.9.x allowing attackers (who control a stub domain kernel or tool stack) to cause a denial of service (host OS crash) because of a missing comparison (of range start to range end) within the DMOP map/unmap implementation. | |||||
