Technical Description
VMware ESXi (6.7 before ESXi670-201904101-SG and 6.5 before ESXi650-201903001), Workstation (15.x before 15.0.3 and 14.x before 14.1.6) and Fusion (11.x before 11.0.3 and 10.x before 10.1.6) contain an out-of-bounds read vulnerability in the pixel shader functionality. Successful exploitation of this issue may lead to information disclosure or may allow attackers with normal user privileges to create a denial-of-service condition on the host. 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.
Remediation
