Descriptions
Datakit Software libraries CatiaV5_3dRead, CatiaV6_3dRead, Step3dRead, Ug3dReadPsr, Jt3dReadPsr modules in KeyShot Versions v10.1 and prior lack proper validation of user-supplied data when parsing STP files. This could result in a stack-based buffer overflow. An attacker could leverage this vulnerability to execute code in the context of the current process.
Las bibliotecas de Datakit Software CatiaV5_3dRead, CatiaV6_3dRead, Step3dRead, Ug3dReadPsr, Jt3dReadPsr en los módulos KeyShot Versiones v10.1 y anteriores carecen de una comprobación apropiada de los datos suministrados por el usuario cuando se analizan archivos STP. Esto podría resultar en un desbordamiento del búfer en la región stack de la memoria. Un atacante podría explotar esta vulnerabilidad para ejecutar código en el contexto del proceso actual
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Siemens Solid Edge Viewer. 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 STP 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 stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
