CVE-2018-3665 6 Canonical, Citrix, Debian and 3 more 14 Ubuntu Linux, Xenserver, Debian Linux and 11 more 2024-11-21 4.7 MEDIUM 5.6 MEDIUM
System software utilizing Lazy FP state restore technique on systems using Intel Core-based microprocessors may potentially allow a local process to infer data from another process through a speculative execution side channel.
CVE-2018-19965 3 Citrix, Debian, Xen 3 Xenserver, Debian Linux, Xen 2024-11-21 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-2018-19962 3 Citrix, Debian, Xen 3 Xenserver, Debian Linux, Xen 2024-11-21 6.9 MEDIUM 7.8 HIGH
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-2018-19961 3 Citrix, Debian, Xen 3 Xenserver, Debian Linux, Xen 2024-11-21 6.9 MEDIUM 7.8 HIGH
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-2018-14007 1 Citrix 1 Xenserver 2024-11-21 10.0 HIGH 9.8 CRITICAL
Citrix XenServer 7.1 and newer allows Directory Traversal.
CVE-2018-11053 4 Citrix, Dell, Redhat and 1 more 4 Xenserver, Emc Idrac Service Module, Enterprise Linux and 1 more 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
Dell EMC iDRAC Service Module for all supported Linux and XenServer versions v3.0.1, v3.0.2, v3.1.0, v3.2.0, when started, changes the default file permission of the hosts file of the host operating system (/etc/hosts) to world writable. A malicious low privileged operating system user or process could modify the host file and potentially redirect traffic from the intended destination to sites hosting malicious or unwanted content.
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-2016-9603 4 Citrix, Debian, Qemu and 1 more 9 Xenserver, Debian Linux, Qemu and 6 more 2024-11-21 9.0 HIGH 5.5 MEDIUM
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-2014-3798 1 Citrix 1 Xenserver 2024-11-21 6.1 MEDIUM 6.5 MEDIUM
The Windows Guest Tools in Citrix XenServer 6.2 SP1 and earlier allows remote attackers to cause a denial of service (guest OS crash) via a crafted Ethernet frame.
CVE-2012-4606 1 Citrix 1 Xenserver 2024-11-21 4.6 MEDIUM 7.8 HIGH
Citrix XenServer 4.1, 6.0, 5.6 SP2, 5.6 Feature Pack 1, 5.6 Common Criteria, 5.6, 5.5, 5.0, and 5.0 Update 3 contains a Local Privilege Escalation Vulnerability which could allow local users with access to a guest operating system to gain elevated privileges.
