JSON

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

Mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
