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.
