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 PRT files. This could lead to pointer dereferences of a value obtained from an untrusted source. 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 de KeyShot Versiones v10.1 y anteriores, carecen de una comprobación apropiada de los datos suministrados por el usuario cuando se analizan archivos PRT. Esto podría conllevar a desreferencias de puntero de un valor obtenido de una fuente no confiable. 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 PRT files. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to execute code in the context of the current process.
