Vulnerability Description
Open CASCADE Technology (OCCT) V8_0_0_rc5 contains multiple vulnerabilities in its IGES and STEP file parsers that can be triggered by crafted IGES or STEP files. These issues include an out-of-bounds read in Geom2d_BSplineCurve::EvalD0 during IGES B-spline curve evaluation, an out-of-bounds read in MakeBSplineCurveCommon during STEP B-spline curve construction, and infinite recursion in StepShape_OrientedEdge::EdgeStart when processing a self-referential OrientedEdge entity. Successful exploitation may result in denial of service or unintended memory disclosure.
