Description

VMware ESXi (6.5 before ESXi650-201710401-BG), Workstation (12.x before 12.5.8), and Fusion (8.x before 8.5.9) contain a vulnerability that could allow an authenticated VNC session to cause a heap overflow via a specific set of VNC packets resulting in heap corruption. Successful exploitation of this issue could result in remote code execution in a virtual machine via the authenticated VNC session. Note: In order for exploitation to be possible in ESXi, VNC must be manually enabled in a virtual machine's .vmx configuration file. In addition, ESXi must be configured to allow VNC traffic through the built-in firewall.

Affected configurations

• vmware workstation pro (>= 12.0.0 < 12.5.8) • vmware workstation pro 14.0 • vmware workstation pro 14.1.0 • vmware esxi 6.5 • vmware fusion (>= 8.0.0 < 8.5.9)
