Oracle Linux: CVE-2020-36242: ELSA-2021-1608: python-cryptography security, bug fix, and enhancement update (MODERATE) (Multiple Advisories)
Description
In the cryptography package before 3.3.2 for Python, certain sequences of update calls to symmetrically encrypt multi-GB values could result in an integer overflow and buffer overflow, as demonstrated by the Fernet class. 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
