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 CATPart files. This could result in an out-of-bounds write past the end of an allocated structure. 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 CATPart. Esto podría resultar en una escritura fuera de límites más allá del final de una estructura asignada. Un atacante podría explotar esta vulnerabilidad para ejecutar código en el contexto del proceso actual
