b. Out-of-bounds write via Cortado ThinPrint

 

VMware Workstation and Horizon View Client contain an out-of-bounds write vulnerability in JPEG2000 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 Client. 

 

VMware would like to thank Anonymous working with Trend Micro's Zero Day Initiative for reporting this issue to us.  

 

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the identifier CVE-2017-4935 to this issue.
