Puppet / Bug PUP-10622
Segmentation fault on start whith high-entropy ASLR
Issue Type: Bug Bug
Affects Versions: PUP 6.17.0
Assignee: Unassigned
Components: Windows
Created: 2020/08/17 1:58 AM
Priority: Normal Normal
Reporter: Sebastian Krysmanski

Puppet Version: 6.17
Puppet Server Version: -
OS Name/Version: Windows 10 x64 (2004)

In my company someone (more paranoid) in the IT department decided that on all of our machines the Windows exploit protection settings have to be changed to:

  • Randomize memory allocations (Bottom-up ASLR): On by default
  • High-entropy ASLR: On by default

With these settings enabled, running even the simplest puppet commands (like `puppet --version`) fails with a segmentation fault:

$ puppet --version
 
C:/Program Files/Puppet Labs/Puppet/puppet/lib/ruby/gems/2.5.0/gems/win32-dir-0.4.9/lib/win32/dir.rb:84: [BUG] Segmentation fault
 
ruby 2.5.8p224 (2020-03-31 revision 67882) [x64-mingw32]

[NOTE]
 
You may have encountered a bug in the Ruby interpreter or extension libraries.
 
Bug reports are welcome.
 
For details: http://www.ruby-lang.org/bugreport.html

You can reproduce this problem by settings both settings mentioned above in the Exploit Protection settings (simply search for "exploit" in Windows search) to On by default (which apparently is different from "Use default (On)"), then reboot and then call `puppet --version`.

Now I know that one can provide exceptions for these settings (although only at the "ruby.exe" level) but in my opinion Puppet should not just crash if these settings are applied (especially since it's not obvious why the crash is happening, especially when these exploit protection settings just get pushed to your device without the user knowing).

Also, I know (or at least guess) that the problem is actually in the win32-dir gem and not in Puppet itself. But it would be nice if you guys could handle the communication to the gem authors (as I'm no ruby developer and would need to learn ruby from scratch to provide a reproducer for the problem - and even then, Puppet is still using the out-dated version 0.4.9 of win32-dir, so Puppet would still need to update its internal gem).

Desired Behavior: Puppet should work

Actual Behavior: Puppet crashes

Re: Segmentation fault on start whith high-entropy ASLR

Hi Sebastian Krysmanski,

We managed to narrow down the issue to a specific function call in win32-dir, and opened a PR to fix the issue: https://github.com/chef/win32-dir/pull/28

As a side note, our next major release, Puppet 7, no longer has a dependency on win32-dir so it's not affected by the issue described in the ticket. Puppet 7 has not been officially released yet, but nightly builds are available here: http://nightlies.puppet.com/downloads/windows/puppet7-nightly/
