VMware ESXi (7.0 before ESXi_7.0.0-1.20.16321839, 6.7 before ESXi670-202006401-SG and 6.5 before ESXi650-202005401-SG), Workstation (15.x before 15.5.2), and Fusion (11.x before 11.5.2) contain a use-after-free vulnerability in PVNVRAM. A malicious actor with local access to a virtual machine may be able to read privileged information contained in physical memory.

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 a use-after-free vulnerability in the SVGA device. A malicious actor with local access to a virtual machine with 3D graphics enabled may be able to exploit this vulnerability to execute code on the hypervisor from a virtual machine.

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 off-by-one heap-overflow vulnerability in the SVGA device. A malicious actor with local access to a virtual machine with 3D graphics enabled may be able to exploit this vulnerability to execute code on the hypervisor from a virtual machine. Additional conditions beyond the attacker's control must be present for exploitation to be possible.

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.

VMware ESXi (6.7 before ESXi670-202004101-SG and 6.5 before ESXi650-202005401-SG), VMware Workstation (15.x before 15.5.2) and VMware Fusion (11.x before 11.5.2) contain a denial-of-service vulnerability in the shader functionality. Successful exploitation of this issue may allow attackers with non-administrative access to a virtual machine to crash the virtual machine's vmx process leading to a denial of service condition.

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.

VMware ESXi (6.7 before ESXi670-201908101-SG and 6.5 before ESXi650-201910401-SG), Workstation (15.x before 15.5.0) and Fusion (11.x before 11.5.0) contain a denial-of-service vulnerability in the shader functionality. Successful exploitation of this issue may allow attackers with normal user privileges to create a denial-of-service condition on their own VM. Exploitation of this issue require an attacker to have access to a virtual machine with 3D graphics enabled. It is not enabled by default on ESXi and is enabled by default on Workstation and Fusion.

VMware ESXi 6.5 suffers from partial denial of service vulnerability in hostd process. Patch ESXi650-201907201-UG for this issue is available.

In the add_match function in libbb/lineedit.c in BusyBox through 1.27.2, the tab autocomplete feature of the shell, used to get a list of filenames in a directory, does not sanitize filenames and results in executing any escape sequence in the terminal. This could potentially result in code execution, arbitrary file writes, or other attacks.
