CVE-2017-4909

Name of the Vulnerable Software and Affected Versions VMware Workstation versions 12.x prior to 12.5.3 Horizon View Client versions 4.x prior to 4.4.0

Description The issue is related to a heap buffer-overflow in the TrueType Font (TTF) parser within the TPView.dll. This could potentially allow a guest to execute code or cause a Denial of Service on the Windows OS running the affected software. The exploitation is contingent upon the virtual printing feature being enabled, which is not enabled by default in Workstation but is enabled by default in Horizon View Client.

Recommendations For VMware Workstation versions 12.x prior to 12.5.3, update to version 12.5.3 or later. For Horizon View Client versions 4.x prior to 4.4.0, update to version 4.4.0 or later. As a temporary workaround, consider disabling the virtual printing feature to minimize the risk of exploitation.
