SECURITY UPDATE: Prevent unauthorised users from setting state events in a room
when there is no `m.room.power_levels` event in force in the room. (PR #3397)
Discussion around the Matrix Spec change proposal for this change can be
followed at https://github.com/matrix-org/matrix-doc/issues/1304.
This appears to have stopped working since matrix.org moved to cloudflare. The
Host header should match the name of the server, not whatever is in the SRV
record.
This is only used by filter_events_for_client, so we can simplify the whole
thing by just doing one user at a time, and removing a dead storage function to
boot.
It has been over a year since any code has been commited. Some of the relevant links in
the documentation are broken, but since no pull requests are being accepted, they
won't get fixed. We should probably remove this from the README.
=======================================
v0.31.1 fixes a security bug in the ``get_missing_events`` federation API
where event visibility rules were not applied correctly.
We are not aware of it being actively exploited but please upgrade asap.
Bug Fixes:
* Fix event filtering in get_missing_events handler (PR #3371)

Changes in synapse v0.31.1 (2018-06-08)
=======================================
v0.31.1 fixes a security bug in the ``get_missing_events`` federation API
where event visibility rules were not applied correctly.
We are not aware of it being actively exploited but please upgrade asap.
Bug Fixes:
* Fix event filtering in get_missing_events handler (PR #3371)
Firstly, don't swallow the reason for the failure
Secondly, don't assume all exceptions are verification failures
Thirdly, log a bit of info about the key being used if debug is enabled
These "temporary fixes" have been here three and a half years, and I can't find
any events in the matrix.org database where the calculated signature differs
from what's in the db. It's time for them to go away.
