HIGH 7.8EPSS 1.98%
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.98%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
