Windows 10: BEX Error when DEP is on

HelloI am trying to recreate a Proof of Concept for a vulnerability CVE-2018-12113. The vulnerable FTP client is installed on a Windows 10 VM. When the Python script is executed and the FTP client is used to connect to the server, the client crashes, which I think is supposed to happen due to buffer overflow. Below is a screenshot for from event viewer. What does BEX mean in this context? I can provide more details if required.

BEX event

BEX = data exception - try adding the program to to a list of exceptions using this dialogue:

Hi James,

BEX errors are typically raised when Windows detects that a program tries to put more data than possible in a region of memory. It's like overfilling a glass with water until the water spills over.

Kindly confirm if this is how you tried to restore files from a backup:

1. Open Backup and Restore by clicking the Start
   button, clicking Control Panel, clicking System and Maintenance, and then clicking
   Backup and Restore.
2. Click Restore my files, and then follow the steps in the wizard.

Also, please send a screenshot of the error you are getting when attempting to restore your files.

Hoping to hear from you soon.

 

64-Bit Operating System Cannot Run Many x86 Applications or Programs

It depends on the program - especially how old it is and whether it's compatible with Win 10.

What you describe is typical of needing to run it in compatibility mode (rt click its shortcut or exe file, click Troubleshoot compatibility).

Another possiblity is a BEX error - see your Reliability History and look at the relevant red X.

That would suggest you need to add it to your DEP exception list.
