GNU Libtasn1-4.13 libtasn1-4.13 version libtasn1-4.13, libtasn1-4.12 contiene una denegación de servicio (DoS). De manera específica, el uso de recursos de CPU llega al 100% cuando se ejecuta asn1Paser contra el POC debido a que existe un problema en _asn1_expand_object_id(p_tree) en el que, después de un período largo de tiempo, el programa se bloquea y se cierra. Este ataque parece ser explotable mediante el análisis sintáctico de un archivo manipulado.
