Summary
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.
