Windows 10 [Version 10.0.19042.1348] x64 - DynamoRIO-Windows-9.0.19216 - VS 2019

[callax2030]

Hello,

I've really tried everything to get this working, and I'm starting to lose my mind. My setup is: Windows 10 [Version 10.0.19042.1348] x64, DynamoRIO-Windows-9.0.19216, and VS 2019. I first tried using the latest version of DynamoRIO, but the winafl.dll file never compiled and ended with errors.

With DynamoRIO 9.0.19216, the compilation works fine, though I get an ASLR warning. So, I have DynamoRIO 9.0.19216 and the Winafl fork compiled with the same version of DynamoRIO, and it should be working.

When I run drrun.exe -c ..\samples\bin64\bbsize.dll -- notepad, it runs fine with no error messages. However, when I try a simple command like c:\DynamoRIO\bin64\drrun.exe -c winafl.dll -- notepad, I always get the same error message: [3488] Unable to load client library: winafl.dll: library initializer failed.

I’ve tried copying winafl.dll into the same directory as c:\DynamoRIO\bin64, and I’ve also tried specifying the full path c:\winafl\build64\bin\Release\winafl.dll. I’ve tried all possible combinations, but the message is always the same. I’m getting really frustrated and upset. I don’t want to bother anyone, so I’ve tried to read and research everything I can.

Bitdefender and Windows 10 security are all Off and no Antivirus on my VM ...

Could someone please help me with this issue? I’d really appreciate it. :(

Cheers,
callaX

I am getting the error too.

I'm on windows 11, using visual studio 2022.

Compiled with:

cmake -G"Visual Studio 17 2022" -A x64 .. -DDynamoRIO_DIR=C:\Users\MakotoEmura\Documents\fuzz-test\DynamoRIO-Windows-10.0.19692\cmake -DUSE_COLOR=1 -DUSE_DRSYMS=1

I wish the error message was more specific so we know where and what failed.

Hello MakotoE,

Give a try to this and let me know, it works for me.

Microsoft Windows [Version 10.0.19045.6466]
DynamoRIO-Windows-9.93.19557
WinAFL (latest version)
cmake -G"Visual Studio 17 2022" -A x64 .. -DDynamoRIO_DIR=C:\DynamoRIO\cmake -DUSE_COLOR=1

I'll try to setup a Win11 box shortly and I'll put my comments here.

Good LuckRegards,

It is also important to lauch the fuzz from Release (your system build version) too. You have to setup your binary environnement, dll's and other needed files to your .exe to run:
cd C:\Users\fuzz\Desktop\winafl\build64\bin\Release
C:\DynamoRIO\bin64\drrun.exe -c winafl.dll -debug -target_module test_gdiplus.exe -target_offset 0x1100 -fuzz_iterations 5 -nargs 2 -- test_gdiplus.exe not_kitty.bmp
