Summer Long 2021-03-17 00:38:10 UTC Doc Text A buffer-overflow flaw was found in the python-cryptography package. In certain sequences of ``update()`` calls when symmetrically encrypting very large payloads (>2GB) could result in an integer overflow, leading to buffer overflows. Note: This fix is a workaround for the OpenSSL CVE-2021-23840 flaw. Source: pyca/cryptography project
