Descriptions

A maliciously crafted DWG file can be used to write beyond the allocated buffer while parsing DWG files. The vulnerability exists because the application fails to handle a crafted DWG file, which causes an unhandled exception. An attacker can leverage this vulnerability to execute arbitrary code.

Un archivo DWG diseñado maliciosamente puede ser usado para escribir más allá del búfer asignado mientras se analizan los archivos DWG. La vulnerabilidad se presenta porque la aplicación comete un fallo para manejar un archivo DWG diseñado, lo que causa una excepción no manejada. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código arbitrario

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Autodesk AutoCAD. 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 parsing of JT files. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process.
