OpenSLP as used in ESXi and the Horizon DaaS appliances has a heap overwrite issue. VMware has evaluated the severity of this issue to be in the Critical severity range with a maximum CVSSv3 base score of 9.8.

Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.

ESXi, Workstation, Fusion, VMRC and Horizon Client contain a use-after-free vulnerability in the virtual sound device. VMware has evaluated the severity of this issue to be in the Important severity range with a maximum CVSSv3 base score of 8.5.

VMware vSphere ESXi (6.7 prior to ESXi670-201810101-SG, 6.5 prior to ESXi650-201811102-SG, and 6.0 prior to ESXi600-201807103-SG) and VMware vCenter Server (6.7 prior to 6.7 U1b, 6.5 prior to 6.5 U2b, and 6.0 prior to 6.0 U3j) contain an information disclosure vulnerability in clients arising from insufficient session expiration. An attacker with physical access or an ability to mimic a websocket connection to a user’s browser may be able to obtain control of a VM Console after the user has logged out or their session has timed out.

VMware ESXi (6.7 before ESXi670-201903001, 6.5 before ESXi650-201903001, 6.0 before ESXi600-201903001), Workstation (15.x before 15.0.4, 14.x before 14.1.7), Fusion (11.x before 11.0.3, 10.x before 10.1.6) contain a Time-of-check Time-of-use (TOCTOU) vulnerability in the virtual USB 1.1 UHCI (Universal Host Controller Interface). Exploitation of this issue requires an attacker to have access to a virtual machine with a virtual USB controller present. This issue may allow a guest to execute code on the host.

VMware ESXi (6.7 before ESXi670-201903001, 6.5 before ESXi650-201903001, 6.0 before ESXi600-201903001), Workstation (15.x before 15.0.4, 14.x before 14.1.7), Fusion (11.x before 11.0.3, 10.x before 10.1.6) contain an out-of-bounds read/write vulnerability in the virtual USB 1.1 UHCI (Universal Host Controller Interface). Exploitation of this issue requires an attacker to have access to a virtual machine with a virtual USB controller present. This issue may allow a guest to execute code on the host.

VMware ESXi 6.7 without ESXi670-201811401-BG and VMware ESXi 6.5 without ESXi650-201811301-BG contain uninitialized stack memory usage in the vmxnet3 virtual network adapter which may lead to an information leak from host to guest.

VMware ESXi 6.7 without ESXi670-201811401-BG and VMware ESXi 6.5 without ESXi650-201811301-BG, VMware ESXi 6.0 without ESXi600-201811401-BG, VMware Workstation 15, VMware Workstation 14.1.3 or below, VMware Fusion 11, VMware Fusion 10.1.3 or below contain uninitialized stack memory usage in the vmxnet3 virtual network adapter which may allow a guest to execute code on the host.

VMware ESXi (6.7 before ESXi670-201810101-SG, 6.5 before ESXi650-201808401-BG, and 6.0 before ESXi600-201808401-BG), Workstation (14.x before 14.1.3) and Fusion (10.x before 10.1.3) contain an out-of-bounds read vulnerability in SVGA device. This issue may allow a guest to execute code on the host.

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.
