FreeBSD : py-matrix-synapse -- malicious push rules may be used for a denial of service attack. (278561d7-b261-11eb-b788-901b0e934d69)

Matrix developers report : 'Push rules' can specify conditions under which they will match, including eventmatch, which matches event content against a pattern including wildcards. Certain patterns can cause very poor performance in the matching engine, leading to a denial-of-service when...
