Steps to reproduce

The attached file is a client-side only page that doesn’t need internet. While testing our product this week we found out that in Edge, latest version, Windows 10 x64, the file being downloaded cannot be opened/saved leading to “Could not download file” msg by Edge, it does not matter how the Blob looks like. Strangely enough this is not reproducible on each hardware, we were testing with at least 5 different machines, on 3 with latest software it doesn’t work, on others it work without problem, so we are having a hard time figuring out what is the problem but it looks like it is an Edge bug since it works on Chrome, Firefox, Opera, IE11. In the attached file when you enter the password 1q2w3e4r you should get a text file downloaded, as described, on some machines Edge won’t be able to open this file. We also were able to reproduce this in a VMs with no Firewall/Antivirus, after resetting Edge data completely, etc. Please if you could try this on your end and advise what we can do to further support the analysis of the problem as we are releasing this product soon.

What I could also see is that when Edge shows the error there is an event log in the system events viewer, reproducible each time, I may copy it tomorrow if you feel that this would help, but could not find anything about the error on the internet.

The other thing to mention is that we are using following line in our html code:
<!-- saved from url=(0014)about:internet -->
On the machines where the issue is reproducible, the issue disappears if we remove the space between “internet” and "–>", or if we change the line endings type in notepad++ from Windows CRLF to Unix for example it also works, when we revert the changes we get the Edge error again. As far as we know the mark of the web should be ignored by Edge and only parsed by IE? It looks like the problem must be related to this line, but of course, we are not sure, it could only be casuality.

Between, when I tried to login to this bug tracking site on my company machine I got the error that I cannot login with my azure account, but you also don’t get any option to select another account to login so I can only update this ticket from my personal private machine!

  • Also testest with Microsoft Edge 44.18362.1.0 Microsoft EdgeHTML 18.18362 and it does not work.

  • Hi David!

    Has all of your testing been on only one machine? Perhaps the failing modules in the report you provided are corrupted on your system.

    Zach

  • As I wrote originally: Strangely enough this is not reproducible on each hardware, we were testing with at least 5 different machines, on 3 with latest software it doesn’t work, on others it works without problem.
    I tested it today again with latest Windows Updates and the problem is still reproducible. It has 100% to do with the line , does Edge search for this line? Not only IE? Because that would be the only explanation I see.

  • *with the line:

  • Hey, why is this text being trimed from the comments?:

  • “saved from url=(0014)about:internet”

  • Hi David!

    Forgive my phrasing. I am trying to determine why it would be reproducible on only some of your machines which is why I suggested that perhaps there are some damaged files. What I meant to ask is are the machines that failing the same ones each time? 

    Could you provide me with your version of Windows and Microsoft Edge so that I can try to recreate the VM that you were able to reproduce this in?

  • This is from my machine, on which it’s reproducible each time:

    Microsoft Edge 44.17763.1.0
    Microsoft EdgeHTML 18.17763
    Windows 10 Enterprise x64 Version 1809

  • I also tryied now starting in safe mode where I now get the same issue but I also get an error dialog with the same message as in the event logs, but the difference is I was not getting this dialos in the normal mode:
    “The system detected an overrun of a stack-based buffer in this application. This overrun could potentialy allow a malicious user gain contorl of this application.”

  • We also have a hyper-V server with a Windows 10 Enterprise VM:
    Version 10.0.18362 Build 18362
    Microsoft Edge 44.18362.1.0
    Microsoft EdgeHTML 18.18362
    Updated with latest updated on 27.05.2019, here the issue is also reproducible.

  • Hi David!

    I tried it out again on a VM running “Windows 10 Enterprise VM:
    Version 10.0.18362 Build 18362
    Microsoft Edge 44.18362.1.0
    Microsoft EdgeHTML 18.18362
    Updated with latest updated on 27.05.2019” and I was still unable to reproduce the issue.

    Would you be able to provide me with an image of the VM that reproduces this?

    Thanks,
    Zach
