Known Vulnerabilities
CVE-2017-4941
VMware ESXi (6.0 before ESXi600-201711101-SG, 5.5 ESXi550-201709101-SG), 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 stack overflow via a specific set of VNC packets. 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.
CVE-2017-4933
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.
CVE-2017-4938
VMware Workstation (12.x before 12.5.8) and Fusion (8.x before 8.5.9) contain a guest RPC NULL pointer dereference vulnerability. Successful exploitation of this issue may allow attackers with normal user privileges to crash their VMs.
CVE-2017-4934
VMware Workstation (12.x before 12.5.8) and Fusion (8.x before 8.5.9) contain a heap buffer-overflow vulnerability in VMNAT device. This issue may allow a guest to execute code on the host.
