我在应用程序中使用 boofuzz 来模糊特定功能。我为我的模糊向量创建的块如下所示：
with s_block("getPasswd"):
s_byte(0, name="usID", fuzzable=False)
s_bytes(value=bytes([0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00]), name="dataChoose", size=16, max_len=16, fuzzable=False) # THIS IS 16 BYTES
s_byte(0,name="paswd", fuzzable=False)
s_byte(0,name="2fA", fuzzable=False)
s_byte(0,name="status", fuzzable=False)
s_word(0x0000, name="subData",fuzzable=False)
s_byte(0,name="adminUsr", fuzzable=True)
s_bytes(value=bytes([0x00]*170),name="hashOfPswd", size=170, max_len=170, fuzzable=False)
在我将hashOfPswd的大小更改为 170 之前，我的 fuzzing 代码运行良好（如您所见）。最初它是 50 并且没有问题，但是在查看了我想要模糊的函数之后，这是大小，因此我必须将其设置为 170。当我这样做时，出现以下错误：

这是 boofuzz 库中的一系列异常。我怀疑tcp_socket_connection.py但这有点奇怪，因为通常 tcp 套接字最多允许 1GB 的数据。
有谁知道如何用这种大小的模糊向量创建这样的块并正确运行它？或者也许我应该改变它以便它能够正常运行？先感谢您
