CVE-2017-4912: VMware Workstation vulnerability

VMware Workstation (12.x prior to 12.5.3) and Horizon View Client (4.x prior to 4.4.0) contain multiple out-of-bounds read vulnerabilities in TrueType Font (TTF) parser in the TPView.dll. On Workstation, this may allow a guest to execute code or perform a Denial of Service on the Windows OS that runs Workstation. In the case of a Horizon View Client, this may allow a View desktop to execute code or perform a Denial of Service on the Windows OS that runs the Horizon View Client. Exploitation is only possible if virtual printing has been enabled. This feature is not enabled by default on Workstation but it is enabled by default on Horizon View.

Security readout for executives and security teams

CVE-2017-4912 affects VMware Workstation and Horizon View Client for Windows. A font parsing flaw in virtual printing can let a malicious guest or View desktop crash, or potentially run code on, the Windows system running the VMware client. Exposure depends on virtual printing being enabled. Most relevant exposure is Windows endpoints running affected VMware Workstation or Horizon View Client versions with virtual printing enabled. Horizon View Client deserves extra attention because the vulnerable feature is enabled by default according to the CVE description. Treat as high priority for legacy VMware desktop virtualization environments. The risk is bounded by product version and virtual printing status, but the possible impact includes code execution on Windows client or host systems. Mitigation focus: Upgrade Workstation to 12.5.3 or later.; Upgrade Horizon View Client for Windows to 4.4.0 or later.; Disable virtual printing where it is not operationally required..
