Hi, The following vulnerability was published for syncthing. CVE-2021-21404[0]: | Syncthing is a continuous file synchronization program. In Syncthing | before version 1.15.0, the relay server `strelaysrv` can be caused to | crash and exit by sending a relay message with a negative length | field. Similarly, Syncthing itself can crash for the same reason if | given a malformed message from a malicious relay server when | attempting to join the relay. Relay joins are essentially random (from | a subset of low latency relays) and Syncthing will by default restart | when crashing, at which point it's likely to pick another non- | malicious relay. This flaw is fixed in version 1.15.0. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
