Hi Vince/Pythonnet,

 

I tested again with Python 3.9.6 which is released on 6/28, still got error when running “pip install pythonnet”.  I got the same error on two machines. How could we solve it?

 

Thanks,

Di

Hi guys,

 

Am I missing something here, because Python.Net v2.5.2 already supports Python 3.9:

 

https://github.com/pythonnet/pythonnet/releases

 

"Additionally, includes support for Python 3.9"

 

Regards,
Vince

Hi Douglas,

 

It looks to me like this was fixed in Python 3.6, 3.7, 3.8 and 3.9:

 

From https://python-security.readthedocs.io/vuln/cjk-codec-download-eval.html:

 

Fixed In

·         Python 3.6.13 (2021-02-16) fixed by commit e912e94 (branch 3.6) (2020-10-20)

·         Python 3.7.10 (2021-02-16) fixed by commit 43e5231 (branch 3.7) (2020-10-20)

·         Python 3.8.7 (2020-12-21) fixed by commit 6c6c256 (branch 3.8) (2020-10-06)

·         Python 3.9.1 (2020-12-07) fixed by commit b664a1d (branch 3.9) (2020-10-06)

So you should be able to address the CVE by upgrading to one of these patch versions. AFAIK we don't have a timeline for 3.9 support in Python for .NET yet.

 

cheers,

-Mark

PythonNet,

                Hi folks, I have no idea if this is the correct way to engage support / ask questions, so please redirect me.  We need to deploy Python v3.9 to resolve a known Security issue in older versions.  I’m told we’re blocked on deploying until PythonNet is updated to support v3.9.  So the question is when might that be?

 

CVE-2020-27619: WIndows

Python versions 3.0.0 through 3.9.0 are susceptible to a vulnerability which when successfully exploited could lead to disclosure of sensitive information, addition or modification of data, or Denial of Service (DoS).

Affected Versions 

Python versions 3.0.0 through 3.9.0 

 

Thanks,
