Synapse Denial of service due to incorrect application of event authorization rules during state resolution
Résumé
Synapse Denial of service due to incorrect application of event authorization rules during state resolution
Description d'origine
La description telle que publiée par la source (souvent en anglais).
Synapse is an open-source Matrix homeserver written and maintained by the Matrix.org Foundation. If Synapse and a malicious homeserver are both joined to the same room, the malicious homeserver can trick Synapse into accepting previously rejected events into its view of the current state of that room. This can be exploited in a way that causes all further messages and state changes sent in that room from the vulnerable homeserver to be rejected. This issue has been patched in version 1.68.0
