HIGH Summary
VMware Workstation (12.x prior to 12.5.3) and Horizon View Client (4.x prior to 4.4.0) contain a heap buffer-overflow vulnerability 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)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

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.
