Detailsinfo

A vulnerability was found in VMware Workstation and Horizon View Client (Virtualization Software) (version now known). It has been declared as critical. This vulnerability affects some unknown processing in the library TPView.dll of the component TTF Parser. The manipulation with an unknown input leads to a integer overflow vulnerability. The CWE definition for the vulnerability is CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

VMware Workstation (12.x prior to 12.5.3) and Horizon View Client (4.x prior to 4.4.0) contain an integer-overflow vulnerability in the True Type Font 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.

The bug was discovered 04/18/2017. The weakness was shared 06/08/2017 by Ke Liu with Tencent (Website). The advisory is available at vmware.com. This vulnerability was named CVE-2017-4913 since 12/26/2016. Local access is required to approach this attack. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit.
