Symmetrically encrypting large values can lead to integer overflow
Impact
When certain sequences of update() calls with large values (multiple GBs) for symetric encryption or decryption occur, it's possible for an integer overflow to happen, leading to mishandling of buffers.
SECURITY ISSUE: Fixed a bug where certain sequences of update() calls when symmetrically encrypting very large payloads (>2GB) could result in an integer overflow, leading to buffer overflows. CVE-2020-36242
