3. Problem Description

a. V4H and V4PA desktop agent privilege escalation vulnerability

The V4H and V4PA desktop agents contain a privilege escalation vulnerability. Successful exploitation of this issue could result in a low privileged windows user escalating their privileges to SYSTEM.

VMware would like to thank Martin Lemay of GoSecure Inc. for reporting this issue to us.

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

Column 5 of the following table lists the action required to remediate the vulnerability in each release, if a solution is available.

 * This agent is also bundled with Horizon 7.4.

 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.
 

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the identifier CVE-2017-4948 to this issue.
  

Column 5 of the following table lists the action required to remediate the vulnerability in each release, if a solution is available.

c. Guest access control vulnerability
  

VMware Workstation and Fusion contain a guest access control vulnerability. This issue may allow program execution via Unity on locked Windows VMs.

VMware Tools must be updated to 10.2.0 for each VM to resolve CVE-2017-4945.
 

VMware Tools 10.2.0 is consumed by Workstation 14.1.0 and Fusion 10.1.0 by default.
