A flaw was found in hw. Non-transparent sharing of branch predictor targets between contexts in some Intel(R) processors may potentially allow an authorized user to enable information disclosure via local access.
An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited.
Variant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall boundary and read privileged memory by conducting targeted cache side-channel attacks.
VMware ESXi 4.0 through 5.1 and ESX 4.0 and 4.1 allow remote attackers to cause a denial of service (NULL pointer dereference) by intercepting and modifying Network File Copy (NFC) traffic.
VMware Tools in VMware Workstation 10.x before 10.0.2, VMware Player 6.x before 6.0.2, VMware Fusion 6.x before 6.0.3, and VMware ESXi 5.0 through 5.5, when a Windows 8.1 guest OS is used, allows guest OS users to gain guest OS privileges or cause a denial of service (kernel NULL pointer dereference and guest OS crash) via unspecified vectors.
A flaw was found in hw. Incomplete cleanup in specific special register write operations for some Intel® Processors may allow an authenticated user to enable information disclosure via local access.
A flaw was found in hw. Incomplete cleanup of multi-core shared buffers for some Intel® Processors may allow an authenticated user to enable information disclosure via local access.
A flaw was found in hw. Incomplete cleanup of microarchitectural fill buffers on some Intel® Processors may allow an authenticated user to enable information disclosure via local access.
A flaw was found in hw. Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type, potentially leading to information disclosure.
Multiple use-after-free vulnerabilities in libxml2 2.5.10, 2.6.16, 2.6.26, 2.6.27, and 2.6.32, and libxml 1.8.17, allow context-dependent attackers to cause a denial of service (application crash) via crafted (1) Notation or (2) Enumeration attribute types in an XML file, as demonstrated by the Codenomicon XML fuzzing framework.
drivers/scsi/bfa/bfacore.c in the Linux kernel before 2.6.35 does not initialize a certain port data structure, which allows local users to cause a denial of service (system crash) via read operations on an fchost statistics file.
Description of problem: If the donor file is an append-only file, we should not allow the operation to proceed, lest we end up overwriting the contents of an append-only file.

Untrusted search path vulnerability in VMware Tools in VMware Workstation before 8.0.4, VMware Player before 4.0.4, VMware Fusion before 4.1.2, VMware View before 5.1, and VMware ESX 4.1 before U3 and 5.0 before P03 allows local users to gain privileges via a Trojan horse tpfc.dll file in the current working directory.
VMware ESXi (6.7, 6.5, 6.0), Workstation (15.x and 14.x) and Fusion (11.x and 10.x) contain a denial-of-service vulnerability due to an infinite loop in a 3D-rendering shader. Successfully exploiting this issue may allow an attacker with normal user privileges in the guest to make the VM unresponsive, and in some cases, possibly result other VMs on the host or the host itself becoming unresponsive.
The configuration of VMware ESX Server 2.x, 2.0.x, 2.1.x, and 2.5.x allows local users to cause a denial of service (shutdown) via the (1) halt, (2) poweroff, and (3) reboot scripts executed at the service console.
VMware ESXi 4.0 through 5.1, and ESX 4.0 and 4.1, does not properly implement the Network File Copy (NFC) protocol, which allows man-in-the-middle attackers to cause a denial of service (unhandled exception and application crash) by modifying the client-server data stream.
The self-extracting installer in the vSphere Client Installer package in VMware vCenter 4.0 before Update 3 and 4.1 before Update 1, VMware ESXi 4.x before 4.1 Update 1, and VMware ESX 4.x before 4.1 Update 1 does not have a digital signature, which might make it easier for remote attackers to spoof the software distribution via a Trojan horse installer.

The CPU hardware emulation in VMware Workstation 6.0.5 and earlier and 5.5.8 and earlier; Player 2.0.x through 2.0.5 and 1.0.x through 1.0.8; ACE 2.0.x through 2.0.5 and earlier, and 1.0.x through 1.0.7; Server 1.0.x through 1.0.7; ESX 2.5.4 through 3.5; and ESXi 3.5, when running 32-bit and 64-bit guest operating systems, does not properly handle the Trap flag, which allows authenticated guest OS users to gain privileges on the guest OS.
Unspecified vulnerability in VMware ESXi 3.5 before ESXe350-200901401-I-SG and ESX 3.5 before ESX350-200901401-SG allows local administrators to cause a denial of service (host crash) via a snapshot with a malformed VMDK delta disk.
The CPU hardware emulation for 64-bit guest operating systems in VMware Workstation 6.0.x before 6.0.5 build 109488 and 5.x before 5.5.8 build 108000; Player 2.0.x before 2.0.5 build 109488 and 1.x before 1.0.8; Server 1.x before 1.0.7 build 108231; and ESX 2.5.4 through 3.5 allows authenticated guest OS users to gain additional guest OS privileges by triggering an exception that causes the virtual CPU to perform an indirect jump to a non-canonical address.
Daniel Veillard discovered that a specially crafted document can lead to a recursive evaluation of entities, the result being an exhaustion of memory and CPU usage

Directory traversal vulnerability in VMware Server 1.x before 1.0.10 build 203137 and 2.x before 2.0.2 build 203138 on Linux, VMware ESXi 3.5, and VMware ESX 3.0.3 and 3.5 allows remote attackers to read arbitrary files via unspecified vectors.
net/unix/afunix.c in the Linux kernel 2.6.31.4 and earlier allows local users to cause a denial of service (system hang) by creating an abstract-namespace AFUNIX listening socket, performing a shutdown operation on this socket, and then performing a series of connect operations to this socket.
The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the current->clearchildtid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONECHILDSETTID or CLONECHILDCLEARTID enabled, which is not properly handled during thread creation and exit.
