Fedora 30: FEDORA-2019-80f1943143 Critical: Matrix-Synapse Security Fixes

Matrix is an ambitious new ecosystem for open federated Instant Messaging and

VoIP. Synapse is a reference "homeserver" implementation of Matrix from the

core development team at matrix.org, written in Python/Twisted. It is intended

to showcase the concept of Matrix and let folks see the spec in the context of

a coded base and let you run your own homeserver and generally help bootstrap

the ecosystem.

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.
