| CVE-2017-12136 | 3 Citrix, Debian, Xen | 3 Xenserver, Debian Linux, Xen | 2024-08-05 | 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 | 2024-08-05 | 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 | 2024-08-05 | 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-2017-2620 | 5 Citrix, Debian, Qemu and 2 more | 12 Xenserver, Debian Linux, Qemu and 9 more | 2024-08-05 | N/A |
| 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 | 12 Xenserver, Debian Linux, Qemu and 9 more | 2024-08-05 | N/A |
| 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-2018-19961 | 3 Citrix, Debian, Xen | 3 Xenserver, Debian Linux, Xen | 2024-08-05 | N/A |
| An issue was discovered in Xen through 4.11.x on AMD x86 platforms, possibly allowing guest OS users to gain host OS privileges because TLB flushes do not always occur after IOMMU mapping changes. | ||||
| CVE-2018-19965 | 3 Citrix, Debian, Xen | 3 Xenserver, Debian Linux, Xen | 2024-08-05 | N/A |
| An issue was discovered in Xen through 4.11.x allowing 64-bit PV guest OS users to cause a denial of service (host OS crash) because #GP[0] can occur after a non-canonical address is passed to the TLB flushing code. NOTE: this issue exists because of an incorrect CVE-2017-5754 (aka Meltdown) mitigation. | ||||
| CVE-2018-19962 | 3 Citrix, Debian, Xen | 3 Xenserver, Debian Linux, Xen | 2024-08-05 | N/A |
| An issue was discovered in Xen through 4.11.x on AMD x86 platforms, possibly allowing guest OS users to gain host OS privileges because small IOMMU mappings are unsafely combined into larger ones. | ||||
| CVE-2018-14007 | 1 Citrix | 1 Xenserver | 2024-08-05 | N/A |
| Citrix XenServer 7.1 and newer allows Directory Traversal. | ||||
| CVE-2018-8897 | 8 Apple, Canonical, Citrix and 5 more | 19 Mac Os X, Ubuntu Linux, Xenserver and 16 more | 2024-08-05 | N/A |
| A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer's Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux kernel crash. The MOV to SS and POP SS instructions inhibit interrupts (including NMIs), data breakpoints, and single step trap exceptions until the instruction boundary following the next instruction (SDM Vol. 3A; section 6.8.3). (The inhibited data breakpoints are those on memory accessed by the MOV to SS or POP to SS instruction itself.) Note that debug exceptions are not inhibited by the interrupt enable (EFLAGS.IF) system flag (SDM Vol. 3A; section 2.3). If the instruction following the MOV to SS or POP to SS instruction is an instruction like SYSCALL, SYSENTER, INT 3, etc. that transfers control to the operating system at CPL < 3, the debug exception is delivered after the transfer to CPL < 3 is complete. OS kernels may not expect this order of events and may therefore experience unexpected behavior when it occurs. | ||||
| CVE-2024-5661 | 1 Citrix | 2 Hypervisor, Xenserver | 2024-08-01 | 6.0 Medium |
| An issue has been identified in both XenServer 8 and Citrix Hypervisor 8.2 CU1 LTSR which may allow a malicious administrator of a guest VM to cause the host to become slow and/or unresponsive. | ||||
