[Bug 1184428] New: VUL-0: CVE-2021-21404: syncthing: relay server `strelaysrv` can be caused to crash and exit by sending a relay message with a negative length field
http://bugzilla.opensuse.org/show_bug.cgi?id=1184428 Bug ID: 1184428 Summary: VUL-0: CVE-2021-21404: syncthing: relay server `strelaysrv` can be caused to crash and exit by sending a relay message with a negative length field Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.2 Hardware: Other URL: https://smash.suse.de/issue/281245/ OS: Other Status: NEW Severity: Minor Priority: P5 - None Component: Basesystem Assignee: screening-team-bugs@suse.de Reporter: abergmann@suse.com QA Contact: security-team@suse.de Found By: Security Response Team Blocker: --- CVE-2021-21404 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.

I checked out https://en.opensuse.org/openSUSE:Maintenance_update_process and have been creating https://build.opensuse.org/request/show/890012 using `osc mr openSUSE:Backports:SLE-15-SP3 syncthing openSUSE:Leap:15.2`. Since there should not be any difference in Leap it makes sense to simply use the SLE backport version, right? Note that I was only dragged into this because I wanted to update Syncthing for TW and the new release happened to fix a CVE. -- You are receiving this mail because: You are on the CC list for the bug.
