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) File "C:\Users\yangzdu.conda\envs\VTMP\lib\site-packages\pymem__init__.py", line 175, in inject_python_shellcode raise RuntimeError('Could not allocate memory for 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.
