VMware Workstation

HGFS.sys in the VMware Tools package in VMware Workstation 5.x before 5.5.6 build 80404, VMware Player before 1.0.6 build 80404, VMware ACE before 1.0.5 build 79846, VMware Server before 1.0.5 build 80187, and VMware ESX 2.5.4 through 3.0.2 does not properly validate arguments in user-mode METHOD_NEITHER IOCTLs to the \\.\hgfs device, which allows guest OS users to modify arbitrary memory locations in guest kernel memory and gain privileges.

Unspecified vulnerability in the VMware Descheduled Time Accounting driver in VMware Workstation 6.5.1 and earlier, VMware Player 2.5.1 and earlier, VMware ACE 2.5.1 and earlier, VMware Server 1.x before 1.0.9 build 156507 and 2.x before 2.0.1 build 156745, VMware Fusion 2.x before 2.0.2 build 147997, VMware ESXi 3.5, and VMware ESX 3.0.2, 3.0.3, and 3.5, when the Descheduled Time Accounting Service is not running, allows guest OS users on Windows to cause a denial of service via unknown vectors.

VMware ESXi (7.0 before ESXi_7.0.0-1.20.16321839, 6.7 before ESXi670-202004101-SG and 6.5 before ESXi650-202005401-SG), Workstation (15.x before 15.5.5), and Fusion (11.x before 11.5.5) contain an out-of-bounds read vulnerability in the Shader functionality. A malicious actor with non-administrative local access to a virtual machine with 3D graphics enabled may be able to exploit this vulnerability to crash the virtual machine's vmx process leading to a partial denial of service condition.

VMware Workstation (15.x before 15.5.2) and Horizon Client for Windows (5.x and prior before 5.4.0) contain a denial-of-service vulnerability due to a heap-overflow issue in Cortado Thinprint. Attackers with non-administrative access to a guest VM with virtual printing enabled may exploit this issue to create a denial-of-service condition of the Thinprint service running on the system where Workstation or Horizon Client is installed.

VMware Workstation 4.0 for Linux allows local users to overwrite arbitrary files and gain privileges via "symlink manipulation."

vmware-config.pl in VMware for Linux, ESX Server 2.x, and Infrastructure 3 does not check the return code from a Perl chmod function call, which might cause an SSL key file to be created with an unsafe umask that allows local users to read or modify the SSL key.

VMWare creates a temporary file vmware-log.USERNAME with insecure permissions, which allows local users to read or modify license information.

VMWare 1.1.2 allows local users to cause a denial of service via a symlink attack.

vmware-authd (aka the Authorization process) in VMware Workstation 10.x before 10.0.5, VMware Player 6.x before 6.0.5, and VMware ESXi 5.0 through 5.5 allows attackers to cause a host OS denial of service via unspecified vectors.

The Host Guest File System (HGFS) in VMware Workstation 10.x before 10.0.5, VMware Player 6.x before 6.0.5, and VMware Fusion 6.x before 6.0.5 and 7.x before 7.0.1 allows guest OS users to cause a guest OS denial of service via unspecified vectors.

VMware Workstation 9.x before 9.0.1, VMware Player 5.x before 5.0.1, VMware Fusion 5.x before 5.0.1, VMware ESXi 4.0 through 5.1, and VMware ESX 4.0 and 4.1 allow guest OS users to cause a denial of service (VMX process disruption) by using an invalid port.

VMware ESXi (6.7 before ESXi670-202004101-SG and 6.5 before ESXi650-202005401-SG), VMware Workstation (15.x before 15.1.0) and VMware Fusion (11.x before 11.1.0) contain a memory leak vulnerability in the VMCI module. A malicious actor with local non-administrative access to a virtual machine may be able to crash the virtual machine's vmx process leading to a partial denial of service.

mount.vmhgfs in the VMware Host Guest File System (HGFS) in VMware Workstation 7.1.x before 7.1.4, VMware Player 3.1.x before 3.1.4, VMware Fusion 3.1.x before 3.1.3, VMware ESXi 3.5 through 4.1, and VMware ESX 3.0.3 through 4.1 allows guest OS users to determine the existence of host OS files and directories via unspecified vectors.

The installer in VMware Workstation 7.x before 7.1.2 build 301548 and VMware Player 3.x before 3.1.2 build 301548 renders an index.htm file if present in the installation directory, which might allow local users to trigger unintended interpretation of web script or HTML by creating this file.

VMware Workstation 5.5.3 34685 does not immediately change the availability of a shared clipboard when the "Enable copy and paste to and from this virtual machine" checkbox is changed, which allows local users to obtain sensitive information or conduct certain attacks that are facilitated by weaker isolation between the host and guest operating systems.

VMware Workstation 5.5.3 34685, when the "Enable copy and paste to and from this virtual machine" option is enabled, preserves clipboard data on the guest operating system after it was deleted on the host operating system, which might allow local users to read clipboard contents by moving the focus back to the host operating system.
