CVE-2017-14319 | 1 Xen | 1 Xen | 2025-04-20 | 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-2016-9380 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
The pygrub boot loader emulator in Xen, when nul-delimited output format is requested, allows local pygrub-using guest OS administrators to read or delete arbitrary files on the host via NUL bytes in the bootloader configuration file. | ||||
CVE-2016-10024 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
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. | ||||
CVE-2016-9379 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
The pygrub boot loader emulator in Xen, when S-expression output format is requested, allows local pygrub-using guest OS administrators to read or delete arbitrary files on the host via string quotes and S-expressions in the bootloader configuration file. | ||||
CVE-2016-9383 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
Xen, when running on a 64-bit hypervisor, allows local x86 guest OS users to modify arbitrary memory and consequently obtain sensitive information, cause a denial of service (host crash), or execute arbitrary code on the host by leveraging broken emulation of bit test instructions. | ||||
CVE-2017-12135 | 3 Citrix, Debian, Xen | 3 Xenserver, Debian Linux, Xen | 2025-04-20 | N/A |
Xen allows local OS guest users to cause a denial of service (crash) or possibly obtain sensitive information or gain privileges via vectors involving transitive grants. | ||||
CVE-2016-10025 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
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. | ||||
CVE-2017-12855 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
Xen maintains the _GTF_{read,writ}ing bits as appropriate, to inform the guest that a grant is in use. A guest is expected not to modify the grant details while it is in use, whereas the guest is free to modify/reuse the grant entry when it is not in use. Under some circumstances, Xen will clear the status bits too early, incorrectly informing the guest that the grant is no longer in use. A guest may prematurely believe that a granted frame is safely private again, and reuse it in a way which contains sensitive information, while the domain on the far end of the grant is still using the grant. Xen 4.9, 4.8, 4.7, 4.6, and 4.5 are affected. | ||||
CVE-2017-15588 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
An issue was discovered in Xen through 4.9.x allowing x86 PV guest OS users to execute arbitrary code on the host OS because of a race condition that can cause a stale TLB entry. | ||||
CVE-2017-15591 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
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. | ||||
CVE-2017-17044 | 1 Xen | 1 Xen | 2025-04-20 | 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 | 2025-04-20 | 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-2017-10914 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
The grant-table feature in Xen through 4.8.x has a race condition leading to a double free, which allows guest OS users to cause a denial of service (memory consumption), or possibly obtain sensitive information or gain privileges, aka XSA-218 bug 2. | ||||
CVE-2017-17563 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
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-2017-7995 | 3 Novell, Suse, Xen | 6 Suse Linux Enterprise Point Of Sale, Suse Linux Enterprise Server, Manager and 3 more | 2025-04-20 | N/A |
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-2016-10013 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
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. | ||||
CVE-2016-9377 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
Xen 4.5.x through 4.7.x on AMD systems without the NRip feature, when emulating instructions that generate software interrupts, allows local HVM guest OS users to cause a denial of service (guest crash) by leveraging IDT entry miscalculation. | ||||
CVE-2016-9382 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
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. | ||||
CVE-2016-9815 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
Xen through 4.7.x allows local ARM guest OS users to cause a denial of service (host panic) by sending an asynchronous abort. | ||||
CVE-2015-7504 | 4 Debian, Qemu, Redhat and 1 more | 5 Debian Linux, Qemu, Enterprise Linux and 2 more | 2025-04-20 | 8.8 High |
Heap-based buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU allows guest OS administrators to cause a denial of service (instance crash) or possibly execute arbitrary code via a series of packets in loopback mode. |
