The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the identifier CVE-2017-4946 to this issue.

 b. Out-of-bounds read issue via Cortado ThinPrint
 
VMware Workstation and Horizon View Client contain an out-of-bounds read vulnerability in TPView.dll. On Workstation, this issue in conjunction with other bugs may allow a guest to leak information from host or may allow for a Denial of Service on the Windows OS that runs Workstation. In the case of a Horizon View Client, this issue in conjunction with other bugs may allow a View desktop to leak information from host or may allow for 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.
   
VMware would like to thank Yakun Zhang of McAfee for reporting this issue to us.
