HIGH Summary
VMware Workstation (12.x prior to 12.5.3) and Horizon View Client (4.x prior to 4.4.0) contain multiple out-of-bounds read vulnerabilities in TrueType Font (TTF) 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.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Overread Buffers An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

NASL family Windows NASL id VMWARE_HORIZON_VIEW_CLIENT_VMSA_2017_0008.NASL description The version of VMware Horizon View Client installed on the remote host is 4.x prior to 4.4.0. It is, therefore, affected by multiple vulnerabilities : - A heap buffer overflow condition exists in the Cortado ThinPrint component, specifically within TPView.dll, due to improper validation of certain input when parsing JPEG2000 files. An attacker on the guest can exploit this to cause a denial of service condition or the execution or arbitrary code on the host system. (CVE-2017-4908) - A heap buffer overflow condition exists in the Cortado ThinPrint component, specifically within TPView.dll, due to improper validation of certain input when parsing TrueType Fonts. An attacker on the guest can exploit this to cause a denial of service condition or the execution or arbitrary code on the host system. (CVE-2017-4909) - Out-of-bounds read and write errors exist in the Cortado ThinPrint component, specifically within TPView.dll, due to improper validation of certain input when parsing JPEG2000 files. An attacker on the guest can exploit these to corrupt memory, resulting in a denial of service condition or the execution of arbitrary code on the host system. (CVE-2017-4910, CVE-2017-4911) - Out-of-bounds read and write errors exist in the Cortado ThinPrint component, specifically within TPView.dll, due to improper validation of certain input when parsing TrueType Fonts. An attacker on the guest can exploit these to corrupt memory, resulting in a denial of service condition or the execution of arbitrary code on the host system. (CVE-2017-4912) - An integer overflow condition exists in the Cortado ThinPrint component, specifically within TPView.dll, due to improper validation of certain input when parsing TrueType Fonts. An attacker on the guest can exploit this to corrupt memory, resulting in a denial of service condition or the execution of arbitrary code on the host system. (CVE-2017-4913) The above vulnerabilities can be exploited only if virtual printing has been enabled. This feature is enabled by default on VMware Horizon View.
