Descriptions

A use-after-free vulnerability exists when reading a DWF/DWFX file using Open Design Alliance Drawings SDK before 2022.11. The specific issue exists with parsing DWF/DWFX files. Crafted data in a DWF/DWFX file and lack of proper validation of input data can trigger a write operation past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.

Se presenta una vulnerabilidad de uso de memoria previamente liberada cuando se lee un archivo DWF/DWFX usando Open Design Alliance Drawings SDK versiones anteriores a 2022.11. El problema específico se presenta al analizar archivos DWF/DWFX. Los datos diseñados en un archivo DWF/DWFX y la falta de comprobación apropiada de los datos de entrada pueden desencadenar una operación de escritura más allá del final de un búfer asignado. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Open Design Alliance (ODA) Drawings Explorer. 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 DWF 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 in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
