Changes in synapse v0.28.0-rc1 (2018-04-26)

Changes in synapse v0.28.1 (2018-05-01)
|
||||
=======================================
|
||||
|
||||
SECURITY UPDATE
|
||||
|
||||
* Clamp the allowed values of event depth received over federation to be
|
||||
[0, 2**63 - 1]. This mitigates an attack where malicious events
|
||||
injected with depth = 2**63 - 1 render rooms unusable. Depth is used to
|
||||
determine the cosmetic ordering of events within a room, and so the ordering
|
||||
of events in such a room will default to using stream_ordering rather than depth
|
||||
(topological_ordering).
|
||||
|
||||
This is a temporary solution to mitigate abuse in the wild, whilst a long solution
|
||||
is being implemented to improve how the depth parameter is used.
