RuntimeError: Could not allocate memory for shellcode in inject_python_shellcode (Python 3.7.16)

[yangzdu]

Description:

I am encountering an error while using the inject_python_shellcode function from the pymem package. The error message indicates that the memory allocation for the shellcode failed.

Environment:

Python version: 3.7.16
pymem version: 1.3
Operating System: Windows
Error Traceback:

arduino
复制代码
Traceback (most recent call last):
File "C:\Users\test.py", line 46, in
print(test_inject_python_shellcode())
File "C:\Users\test.py", line 38, in test_inject_python_shellcode
pm.inject_python_shellcode(shellcode)

RuntimeError: Could not allocate memory for shellcode
Code to Reproduce:

python
复制代码
import pymem

def test_inject_python_shellcode():
notepad = subprocess.Popen(['notepad.exe'])

pm = pymem.Pymem('notepad.exe')
pm.inject_python_interpreter()

# test already injected
pm.inject_python_interpreter()

assert pm.py_run_simple_string

filepath = os.path.join(os.path.abspath('.'), 'pymem_injection.txt')
filepath = filepath.replace("\\", "\\\\")

shellcode = """

f = open("{}", "w+")
f.write("2131313")
f.close()
""".format(filepath)
pm.inject_python_shellcode(shellcode)

assert os.path.exists(filepath)

os.remove(filepath)
notepad.kill()

Create a new Python file with the code above.
Replace 'some_process.exe' with the actual process you are targeting.
Replace b'...' with the actual shellcode.
Run the script.
Expected Behavior:
The shellcode should be injected without any errors.

Actual Behavior:
The script raises a RuntimeError indicating that it could not allocate memory for the shellcode.

Additional Context:
I have tried different processes and shellcodes, but the error persists. Any help or suggestions would be greatly appreciated.
