Descriptions

VT-Designer Version 2.1.7.31 is vulnerable by the program reading the contents of a file (which is already in memory) into another heap-based buffer, which may cause the program to crash or allow remote code execution.

VT-Designer, en su versión 2.1.7.31, es vulnerable a que el programa lea el contenido de un archivo (que ya está en la memoria) en otro búfer basado en memoria dinámica (heap), lo que podría provocar que el programa se cierre inesperadamente o permita la ejecución remota de código.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of INVT VT-Designer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the processing of pm3 files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
