Summary

The original issue was that there was a potential memory corrution
vulnerability. However, the change introduced a regression due to
incorrectly backporting upstream's patch to the (older) version in
Debian LTS.

For Debian 10 buster, this problem has been fixed in version
2.6.1-3+deb10u4.

We recommend that you upgrade your python-cryptography packages.
