Dear!
I was doing some tests with a line to fuzzing firefox.
I wanted to try it and I also wanted to try doing a brute force of offset, the question that I tried with everyone and always gives me the same error, do you know why it is?
Error:
[-] PROGRAM ABORT : Error opening pidfile.txt

First time I see this error, but in general, the pid file is created in
https://github.com/googleprojectzero/winafl/blob/master/afl-fuzz.c#L2302
with -pidfile dynamorio flag. Perhaps instrumentation fails for some reason. These issues can be debugged by running the target in DynamoRIO directly (see the -debug mode in Readme).
Looking at the command line, the most likely reason I can see for instrumentation failing is the target path containing spaces, and not being quoted. It should probably be
«C:Program FilesMozilla Firefoxfirefox.exe»
instead of
C:Program FilesMozilla Firefoxfirefox.exe
Also, I would be really surprised if you could fuzz the whole of firefox (rather than a specific part) in this way and also if you could bruteforce a (meaningful) target_offset.
I meet the same issue, I solved this by open «cmd.exe» with administrator.
Hi, I also meet the same issue. I just test a very simple C program to make sure it works. The program simply reads from a file to check if it’s ‘bad!’. If so, then crashes. When I run WinAFL with static instrumentation mode -Y, it also shows «All programs time out.» issue.
Line:

I’m not sure if this is related to this issue but your command line seems to be missing some required instrumentation flags (such as target module/function, number of function arguments and number of iterations). You should always run the debug mode first (see https://github.com/googleprojectzero/winafl/blob/master/readme_dr.md) and only run afl-fuzz if the debug log looks good.
@yuexizhumeng
The solution is change D:Workspaceswinaflprogramstestprog.exe to «D:Workspaceswinaflprogramstestprog.exe» like says @xinali
I was receiving the same error. I was mistakenly using DynamoRio bin32 executable instead of bin64.
The path string is the key。I also meet this error。
I have encountered the same problem. Have you solved this problem? The following is my command parameters and error message

I have tested the above methods. I have received the same results on both windows7 x86 and x64, and I started cmd.exe with Administartor.
Hi Taolaw,
As @anshuman-goel mentioned earlier, and because I lost a few minutes trying
to figure out what’s wrong, you are using wrong architecture for the DynamoRIO.
If it’s x86 make sure you use the bin32drrun.exe and bin32afl-fuzz.exe,
and consequently if it’s x64 use bin64drrun.exe and bin64afl-fuzz.exe.
From your command line above, it looks like you have compiled for x86 architecture.
Hope that helps,
Symeon
I am getting this same problem regardless of the combination of dynamoRIO and winafl that I use. I’m starting to wonder if the problem isn’t deeper than that, but digging into the .c file doesn’t illuminate the situation much.
I had a similar problem (pidfile error) with a command of the form
afl-fuzz.exe … -- -coverage_module … -- pathtoapp.exe someArg pathtosomeotherfile @@
I had to wrap each whitespace-separated part after the second -- in quotes, like so:
afl-fuzz.exe … -- -coverage_module … -- "pathtoapp.exe" "someArg" "pathtosomeotherfile" @@
It took me a while to figure it out because someArg was a simple number like 1000, so I had not expected to have to wrap it in quotes.
I met a similar problem (pidfile opening error) when I try to fuzz my application with below command:
afl-fuzz.exe -i in -o out -D «D:winaflDynamoRIO-Windows-8.0.0-1bin64» -t 20000 — -coverage_module «pathto*.dll» -coverage_module «pathtomyapp.exe» -fuzz_iterations 10 -target_module «pathtomyapp.exe» -target_offset 0x16e0 -nargs 2 — «pathtomyapp.exe» «-i» @@
myapp.exe also has a parameter «-i» to run it.

PROGRAM ABORT : All test cases time out, giving up! about winafl HOT 3 CLOSED
You’re missing a lot of mandatory instrumentation options, please see the readme.
In any case you should always first run the debug mode (also described in readme) before running afl-fuzz to make sure everything is working correctly.

WinAFL Crashes with testing code about winafl HOT 15 OPEN
ivanfratric commented on January 16, 2023
Which WinAFL version are you using?
I’m not sure this is the cause of your crash, but
-target_module should take just the name, not a path, so -target_module FuzzSample.exe
-nargs is missing (unless it’s intended to be 0)
Does the debug log get created at all?
Can you run your target under DynamoRIO but without WinAFL like this:

ivanfratric commented on January 16, 2023
Wait, how can you get the same error when the command line doesn’t incude WinAFL at all and the error log references winafl.dll (that shouldn’t even exist in the same address space). Can you doublecheck and try again? Your error log also references test_gdiplus.exe that isn’t present anywhere in the command line.

Hmm in that case the issue seems to be with how DR interacts with your target and not in WinAFL. Can you try disabling your antivirus? Antivirus software caused similar issues in the past.

Seems like it. Can you confirm which version of DR would work perfectly with winafl?
I don’t have any antivirus, just windows defender but I don’t think that’s interfering here.

Please see «WinAFL runs slower than expected» in the FAQ section of the readme. I’d say that «return;» without first closing the file is the problem.

Yes. That was the problem. Thanks ivanfrantic.

@ivanfratric Is there any tool or feature for visualization of code coverage?
I can’t see if my code is reaching certain function or not.

@0vercl0k I have to do it automatically also can’t afford IDA Pro as of now. Nice tool btw, useful during CTFs for sure.
Looking for something like https://github.com/mrash/afl-cov if there is, otherwise I will have to write it myself.
ivanfratric commented on January 16, 2023
@iN3O I’d also suggest filing a bug with DynamoRIO and mention yo have an app that works fine on DR 6 but crashes on DR 7, perhaps DR devs will be interested in this.
ksloven commented on January 16, 2023
Hi, I have the same issue with both winafl and dynamorio crashing with «internal crash; program aborted» as reported above. Following the thread, i thought it was because I used dynamorio 7 but I downloaded and used Dynamorio6 and still get same error.
Anti-virus (defender) disabled from real-time scanning.
Even running it directly with drrun, I still get the same error (and its not just adobe, almost any binary I have run thus far).

Dear!
I was doing some tests with a line to fuzzing firefox.
I wanted to try it and I also wanted to try doing a brute force of offset, the question that I tried with everyone and always gives me the same error, do you know why it is?

First time I see this error, but in general, the pid file is created in
https://github.com/googleprojectzero/winafl/blob/master/afl-fuzz.c#L2302
with -pidfile dynamorio flag. Perhaps instrumentation fails for some reason. These issues can be debugged by running the target in DynamoRIO directly (see the -debug mode in Readme).
Looking at the command line, the most likely reason I can see for instrumentation failing is the target path containing spaces, and not being quoted. It should probably be
«C:Program FilesMozilla Firefoxfirefox.exe»
instead of
C:Program FilesMozilla Firefoxfirefox.exe
Also, I would be really surprised if you could fuzz the whole of firefox (rather than a specific part) in this way and also if you could bruteforce a (meaningful) target_offset.
I meet the same issue, I solved this by open «cmd.exe» with administrator.
Hi, I also meet the same issue. I just test a very simple C program to make sure it works. The program simply reads from a file to check if it’s ‘bad!’. If so, then crashes. When I run WinAFL with static instrumentation mode -Y, it also shows «All programs time out.» issue.
Line:
afl-fuzz.exe -i D:Workspaceswinafltestcase -o D:Workspaceswinaflfindings -D D:SoftwareDynamoRIObin64 -t 20000 — -coverage_module testprog.exe — D:Workspaceswinaflprogramstestprog.exe @@
I’m not sure if this is related to this issue but your command line seems to be missing some required instrumentation flags (such as target module/function, number of function arguments and number of iterations). You should always run the debug mode first (see https://github.com/googleprojectzero/winafl/blob/master/readme_dr.md) and only run afl-fuzz if the debug log looks good.
@yuexizhumeng
The solution is change D:Workspaceswinaflprogramstestprog.exe to «D:Workspaceswinaflprogramstestprog.exe» like says @xinali
I was receiving the same error. I was mistakenly using DynamoRio bin32 executable instead of bin64.
The path string is the key。I also meet this error。
I have encountered the same problem. Have you solved this problem? The following is my command parameters and error message

I have tested the above methods. I have received the same results on both windows7 x86 and x64, and I started cmd.exe with Administartor.
Hi Taolaw,
As @anshuman-goel mentioned earlier, and because I lost a few minutes trying
to figure out what’s wrong, you are using wrong architecture for the DynamoRIO.
If it’s x86 make sure you use the bin32drrun.exe and bin32afl-fuzz.exe,
and consequently if it’s x64 use bin64drrun.exe and bin64afl-fuzz.exe.
From your command line above, it looks like you have compiled for x86 architecture.
Hope that helps,
Symeon
I am getting this same problem regardless of the combination of dynamoRIO and winafl that I use. I’m starting to wonder if the problem isn’t deeper than that, but digging into the .c file doesn’t illuminate the situation much.
I had a similar problem (pidfile error) with a command of the form
afl-fuzz.exe … -- -coverage_module … -- pathtoapp.exe someArg pathtosomeotherfile @@
I had to wrap each whitespace-separated part after the second -- in quotes, like so:
afl-fuzz.exe … -- -coverage_module … -- "pathtoapp.exe" "someArg" "pathtosomeotherfile" @@
It took me a while to figure it out because someArg was a simple number like 1000, so I had not expected to have to wrap it in quotes.
I met a similar problem (pidfile opening error) when I try to fuzz my application with below command:
afl-fuzz.exe -i in -o out -D «D:winaflDynamoRIO-Windows-8.0.0-1bin64» -t 20000 — -coverage_module «pathto*.dll» -coverage_module «pathtomyapp.exe» -fuzz_iterations 10 -target_module «pathtomyapp.exe» -target_offset 0x16e0 -nargs 2 — «pathtomyapp.exe» «-i» @@
myapp.exe also has a parameter «-i» to run it.
Don’t know why it does not work.

sssd refuses to start when pidfile is present, but the process is gone
Closed: Fixed
5 years ago
Opened 5 years ago
by laggyluke.
Hmm, I haven’t tried to reproduce this issue, but it does sound like a bug, because the pidfile() function explicitly calls kill(pid, 0) to find out if the process with the number in the pidfile exists..
I was able to reproduce this one on a quick test. Didn’t check any further than «yes, I can reproduce the issue», though.
I do not think it is a bug. It is just wrong use-case.
pkill -KILL -F /var/run/sssd.pid is a wrong way how to stop sssd.
Anyway in case of container and some shared directories there needn’t be process with PID stored in /var/run/sssd.pid due to namespaces. So if you can see message «pidfile exists at /var/run/sssd.pid» then there is something fishy. and sssd should not try to clean this file itself. Such case should be investigated and file manually removed after finding + fixing reason/problem.
Anyway, we might enhance debug/error message.
I completely agree that killing sssd like that is a wrong use-case, obviously I only used it as an example of hard failure that results in a dangling pidfile. In my specific case it was OOM-killed — server misconfiguration plus some bad luck. But it would be great if sssd could be simply restarted by systemd instead of having to reboot the whole server.
I found the bit of code that apparently does the right thing:
https://github.com/SSSD/sssd/blob/0fba03cab9580cab6898e855bcd0ca9b2e54ce67/src/util/server.c#L181
Unfortunately my C skills are not good enough to prepare a pull request, although I might give it a try if noone else is interested.

You needn’t reboot whole server. You need to investigate thing a bit and find out why pid file exists. So in your case you will need to just remove pidfile.
and start sssd.
This is a reason why better error message might make it clear. But as i wrote in previous message. It needn’t be straightforward in container world.
BTW which version of sssd do you use? becasue later version of sssd use systemd + type notify and pidfile needn’t be use there.
I was able to reproduce this in a fresh VM running CentOS Linux release 7.3.1611 (Core) and sssd v1.15.2.
After further investigation we found out that in our setup sssd was hard killed after not being able to gracefully shut down in time on an overloaded server. But I still believe the actual reason for a hard kill is irrelevant. One way or another, we end up in a situation where the pidfile exists, but the corresponding process is no longer running. The pidfile can even be empty and it will still refuse to start.
I’m not sure I fully understand the container case that you’ve mentioned, but it looks like you’re describing a setup that has a pid namespace isolation together with a shared filesystem — is that actually a setup you want to support?

This version of CentOS has sssd 1-14 by default.

Following steps should be sufficient workaround. sssd creates pidfile even though we moved from Type forking -> notify. So pid file is cleaned by SSSD in most cases but systemd does not know anything about it and cannot clean the file in case of corner cases (OOM …)
- echo -e ‘[Service]nPIDFile=/var/run/sssd.pidn’ > /etc/systemd/system/sssd.service.d/sssd_pidfile.conf
- systemctl daemon-reload
- systemctl restart sssd.service
I still am not sure whether it is bug or feature 
Because current state allows us to return back to «Type=forking» for testing purposes.
That’s exactly the kind of workaround that we’re going to use, thanks!
But there’s one more argument to fixing this on sssd side without relying on systemd or any other init system:
If sssd creates a pidfile in the first place, it is probably reasonable to expect it to take full ownership of the whole lifecycle around that pidfile, including cleaning up the stale one in case something goes wrong.

sssd takes care of PIDfile but it does not have a chance in case of OOM.
And as i mentioned few times we cannot remove files due to container use case.
Because containers usually have different PID namespace and we cannot say whether file is leftover after force shutdown (kill -9; OOM …) or files was created by different process in different PID namespace.
Lukas said he would tune the default systemd unit file, but nonetheless, this is a minor issue.

Во-первых, обзор Winafl
Winafl — версия Windows AFL. AFL хочет быть не измельченным, но AFL не поддерживает платформу Windows, поэтому существует отличный бог для пересадки AFL на платформу Windows, которая является Winafl. AFL достигает своих функций, составив ворс и генетический алгоритм. Из-за взаимосвязей поддержки платформы склада в WinaFLL заменяется динамио динамической вставки вставки, а API Windows переписан. Так winafl = AFL + DynamoRio.
При использовании Winafl, чтобы сделать незма, вам необходимо указать целевую программу и соответствующий файл корпуса ввода теста, и должна быть такая целевая функция для вставленных свай. Эта функция включает в себя открытие и закрытие входного файла и анализа файла. Такие после обработки кучи можно гарантировать файл выполнения файла выполнения целевой программы, чтобы избежать повторного создания нового целевого процесса каждый раз, когда вновь создана разжигательная операция. В то же время входные файлы незма преобразуются в соответствии с соответствующим алгоритмом, и он определяется, используется ли охват целевого модуля для последующих незвающих операций.
Во-вторых, установка среды
1. Скачать winafl (https://github.com/ivanfratric/winafl), загруженный код сама содержит сборкущую версию, в том числе 32-битную и 64-битную, вы также можете составить его самостоятельно, так легко понять, изменить, модифицировать и использовать Winafl.
2. Скачать CMake (http://www.cmake.org), сборник Winafl требует CMake, Cmake — это программное обеспечение для перекрестной платформы. Установите Cmake, обратите внимание на автоматическое создание переменных среды при установке.
3. Скачать Dynamoorio (http://dynamorio.org/), кроссплатформенная платформа с открытым исходным кодом анализа динамического инструментального программного обеспечения для инструмента.
4. Затем вам нужен компилятор, вы можете использовать Visual Studio C ++, версия проблемы связана с Cmake, загружая последнюю модель Cmake, поддержку VS 2005-2015, но поскольку VS 2010 не полностью совместима с C99, так когда Компиляция, в STDINT не будет найдено ошибок. Вы можете скопировать один из других и C99 совместимых компиляторов, таких как MINGW, или поиск непосредственно из онлайн.
5. Реконструкция, пожалуйста, обратитесь к описанию Winafl в Github.
For a 32-bit build:
mkdir build32
cd build32
cmake -G"Visual Studio 15 2017" .. -DDynamoRIO_DIR=..pathtoDynamoRIOcmake -DINTELPT=1
cmake --build . --config Release
For a 64-bit build:
mkdir build64
cd build64
cmake -G"Visual Studio 15 2017 Win64" .. -DDynamoRIO_DIR=..pathtoDynamoRIOcmake -DINTELPT=1
cmake --build . --config Release
В-третьих, используйте опыт
Окружающая среда Win7, не запустилась на Win10
1.fuzz winafl тестовая программа test_gdiplus.exe
Сначала нам нужно определить целевую функцию незма, которая устанавливает -target_offset или -Target_Method, соответствующий параметрам. В этом примере основная функция представляет собой условную целевую функцию. Чтобы использовать -target_offset, вы можете просто просматривать смещение этой функции, этот пример равен 0x1680 (адрес начала IDA по умолчанию — 0x400000).
Введите каталог winafl bin32, создайте папку, вставьте копию файла BMP под bmp testCases Images BMP в каталог, который только что создан.
Если есть файл символа, вы можете напрямую установить параметры atarget_method в качестве основного, в противном случае вам нужно будет использовать Target_offset, и оба не могут использоваться одновременно. Для параметров -Coverage_Module мы можем выполнить следующую команду, чтобы получить его, обратите внимание, что каталог Dynamorio должен быть установлен в соответствии с фактической ситуацией. Модуль, загруженный во время реализации целевой программы, приведен в полученном файле журнала.
В текущем каталоге появится следующий файл, этот файл журнала фактически записывает модуль, загруженный во время теста Test_gdiplus.exe, и изменение положения функции смещения записано.
Затем мы можем ввести следующую команду, чтобы сделать незрение, «@@@» означает файл тестового случая, чтобы быть разбитым в каталоге в каталоге.
Результаты каждого этапа в пупугах будут сохранены в каталоге OUT, установленном опцией -O -O, где каталог сбоя или зависания сохраняет файл тестирования ошибок, как для доступной программы назначения Доступно уязвимость требует дальнейшего подтверждения.
