| CVE-2018-19965 | 3 Citrix, Debian, Xen | 3 Xenserver, Debian Linux, Xen | 2024-02-04 | 4.7 MEDIUM | 5.6 MEDIUM |
| 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-2016-9603 | 4 Citrix, Debian, Qemu and 1 more | 9 Xenserver, Debian Linux, Qemu and 6 more | 2024-02-04 | 9.0 HIGH | 9.9 CRITICAL |
| A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support before 2.9; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process. | |||||
| CVE-2018-14007 | 1 Citrix | 1 Xenserver | 2024-02-04 | 10.0 HIGH | 9.8 CRITICAL |

| CVE-2018-8897 | 8 Apple, Canonical, Citrix and 5 more | 11 Mac Os X, Ubuntu Linux, Xenserver and 8 more | 2024-02-04 | 7.2 HIGH | 7.8 HIGH |
| 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-2018-3665 | 6 Canonical, Citrix, Debian and 3 more | 14 Ubuntu Linux, Xenserver, Debian Linux and 11 more | 2024-02-04 | 4.7 MEDIUM | 5.6 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. | |||||
