We've just been alerted that this update fixes a security vulnerability:
Sourced from The GitHub Security Advisory Database.
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.Patches
This is patched in version 3.3.2 and newer.

Affected versions: [">= 3.1, < 3.3.2"]
A newer version of cryptography exists, but since this PR has been edited by someone other than Dependabot I haven't updated it. You'll get a PR for the updated version as normal once this PR is merged.
OK, I won't notify you again about this release, but will get in touch when a new version is available.
If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
