Descriptions

Datakit Software libraries CatiaV5_3dRead, CatiaV6_3dRead, Step3dRead, Ug3dReadPsr, Jt3dReadPsr modules in KeyShot Versions v10.1 and prior are vulnerable to an out-of-bounds read, which may allow an attacker to execute arbitrary code.

Las bibliotecas de Datakit Software CatiaV5_3dRead, CatiaV6_3dRead, Step3dRead, Ug3dReadPsr, Jt3dReadPsr en los módulos de KeyShot Versiones v10.1 y anteriores, son vulnerables a una lectura fuera de límites, lo que puede permitir a un atacante ejecutar código arbitrario

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 JT files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process.
