Summary
GNU Libtasn1-4.13 libtasn1-4.13 version libtasn1-4.13, libtasn1-4.12 contains a DoS, specifically CPU usage will reach 100% when running asn1Paser against the POC due to an issue in _asn1_expand_object_id(p_tree), after a long time, the program will be killed.

De manera espec\u00edfica, 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, despu\u00e9s de un per\u00edodo largo de tiempo, el programa se bloquea y se cierra. Este ataque parece ser explotable mediante el an\u00e1lisis sint\u00e1ctico de un archivo manipulado."
