| 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-2016-9386 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
| The x86 emulator in Xen does not properly treat x86 NULL segments as unusable when accessing memory, which might allow local HVM guest users to gain privileges via vectors involving "unexpected" base/limit values. | ||||
| 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-2016-9380 | 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-2017-12136 | 3 Citrix, Debian, Xen | 3 Xenserver, Debian Linux, Xen | 2025-04-20 | N/A |
| Race condition in the grant table code in Xen 4.6.x through 4.9.x allows local guest OS administrators to cause a denial of service (free list corruption and host crash) or gain privileges on the host via vectors involving maptrack free list handling. | ||||
| CVE-2017-5572 | 1 Citrix | 1 Xenserver | 2025-04-20 | N/A |
| An issue was discovered in Linux Foundation xapi in Citrix XenServer through 7.0. An authenticated read-only administrator can corrupt the host database. | ||||
| CVE-2017-5573 | 1 Citrix | 1 Xenserver | 2025-04-20 | N/A |
| An issue was discovered in Linux Foundation xapi in Citrix XenServer through 7.0. An authenticated read-only administrator can cancel tasks of other administrators. | ||||
| 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-2015-7704 | 6 Citrix, Debian, Mcafee and 3 more | 16 Xenserver, Debian Linux, Enterprise Security Manager and 13 more | 2025-04-20 | 7.5 High |
| The ntpd client in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service via a number of crafted "KOD" messages. | ||||
| CVE-2015-7705 | 4 Citrix, Netapp, Ntp and 1 more | 10 Xenserver, Clustered Data Ontap, Data Ontap and 7 more | 2025-04-20 | 9.8 Critical |
| The rate limiting feature in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to have unspecified impact via a large number of crafted requests. | ||||
| CVE-2016-9385 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
| 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. | ||||
| 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-2016-10025 | 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. | ||||

| 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-2016-9637 | 2 Citrix, Redhat | 2 Xenserver, Enterprise Linux | 2025-04-20 | N/A |
| The (1) ioport_read and (2) ioport_write functions in Xen, when qemu is used as a device model within Xen, might allow local x86 HVM guest OS administrators to gain qemu process privileges via vectors involving an out-of-range ioport access. | ||||
