La biblioteca Raptor RDF Syntax desde la 2.0.15 hasta la 2.0.16 contiene una vulnerabilidad de desbordamiento de búfer basado en el heap en raptor_new_term_from_counted_literal(), causada por el truncamiento de la longitud de la etiqueta de idioma a un unsigned char. Los atacantes pueden proporcionar documentos Turtle, TriG, N-Triples o N-Quads con etiquetas de idioma de 256 bytes o más para corromper la memoria heap, bloquear aplicaciones y, posiblemente, ejecutar código.
