Hi Leo!  Thanks for the reply.  Thanks for the compiling guide! 

Patched edition available at http://software.run.place
Macros are disabled.  New Throwback15 template added.

Is there a way to do New Folder with macros off?

Hey Danny! It's nice you did your custom version. I'm glad you liked and found my guide to compiling HFS helpful. The following message below is what I wrote yesterday before going to sleep (replying your original message), which I'll leave here anyway...

Hi Leo!  Thanks for the reply. 

Is it possible to get a patched copy of HFS 2.3K, 2.3L or even 2.3M?
The "K" and "L" withstand gigabit slightly better than the "M" version.
However, I don't need 2.4 because it locks up under gigabit load.

So, file download location of patched HFS 2.3 ?

• Officially, there isn't a "patched" version of ANY version of the whole version 2 (since Rejetto, is now focused on the new version 3), nor do I have any (personal) version ready to share (if I had it, I would gladly share it, but I still have nothing ready).
• Unofficially, anyone can compile HFS from the source code and modify it to avoid this vulnerability. You'd need a copy of 'Turbo Delphi' or some later version, though. You can check my tutorial "How to compile HFS" if you wish.
  

Sadly, I don't have the time to continue with this anymore, at least for the foreseeable future. I only have like 10 or 20 minutes a day to reply to messages, and programming just takes up way too much time – time I don't have right now. It's not a lack of motivation, but circumstances beyond my control (my parents' health), that are keeping me from continue working on this. I just can't give you any date on when I'll have free time again to get back to this, but don't lose hope!. And thanks for your hosting offer, I appreciate it.

You can try some of the other 'code change' suggestions I've left on this thread (if you want to compile the source code yourself, but you will be on your own with this), or, even better, use another "fork" (unofficial version) of HFS, like any of the options described in this thread. But, what version you choose is totally up to you. The easiest option right now is to just stick with any -official- HFS version 2 (preferably the latest), with macros disabled for now. Or, you could always upgrade to HFS 3 to make Rejetto happy!

For patched version of HFS2.3K, I've added many layers of defense. . . and *Might have solved/reduced the gigabit freeze problem.

locate hfs23-K-patched.zip and you can test it out. 
The site to download it, is running that same copy of HFS2.3K, with the macros on.

Speedup: 
locate hfs23-K-patched3.zip and you can test it out.

Thanks to Leo for help in bypassing the always-on limiters, and this prevents freezes.  Also, I raised the console TTL so the UI stays responsive. 

 Edit:  For round 3:  Thanks to Leo for updated code that blocks hfs-specific attack, in the .exe, without reliance on any particular template.  So, you can use any template that you want to.
 
Included in the zip file is now the legacy default template for HFS2.3M, and I have altered it slightly, so it can run well on the security-patched edition of HFS2.3K.  There is the unicode font added to the stylesheet, some necessary size adjustment, and it does not overwork the system icon code.

Thanks, Danny, for the acknowledgment, I appreciate it.

My only contribution was two small code tweaks, which I’ve shared here in case anyone is interested in reviewing or using them.

Keep up the good work!
Cheers,
Leo.-

HFS2.3N is released
And the server you'd download from is running the same version of HFS2.3N

It has:
Added security filter from Leo (result is auto ban) for hfs-specific
Added security filters from me (result inactivated) for unspecified
Added Leo's skip the loop filter for graph workload (no load if feature unused)
Added Leo's skip the loop filter for limiter workload (reduced load if feature unused)
Shielded archive links (logged-in users who can delete may archive, bots cannot)
Removed version "M" bugged headers mod (to avoid disrupting the data flow)
Removed operationally reliant hardcoded external reference (was outdated)
