Descriptions
Buffer overflow in PJSUA API when calling pjsua_call_dump. An attacker-controlled 'buffer' argument may cause a buffer overflow, since supplying an output buffer smaller than 128 characters may overflow the output buffer, regardless of the 'maxlen' argument supplied

Un argumento "buffer" controlado por un atacante puede causar un desbordamiento de búfer, ya que el suministro de un búfer de salida menor de 128 caracteres puede desbordar el búfer de salida, independientemente del argumento "maxlen" suministrado
