"This release includes four security fixes :

  - Prevent an attack where a federated server could send
    redactions for arbitrary events in v1 and v2 rooms.

  - Prevent a denial-of-service attack where cycles of
    redaction events would make Synapse spin infinitely.

  - Prevent an attack where users could be joined or parted
    from public rooms without their consent.

  - Fix a vulnerability where a federated server could spoof
    read-receipts from users on other servers.

See https://github.com/matrix-org/synapse/releases/tag/v1.2.1 for
complete details.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as
possible without introducing additional issues."
