If you suspect that the result above is incorrect, try re-doing that job on the test case report page.
Clusterfuzz sometimes confuses me.  My understanding is that there's nothing to do here now?

This medium+ severity security issue is a regression on trunk.

Please fix this asap. If you are unable to look into this soon, please revert your change.

Heya meacer@ - clusterfuzz is confusing me.  Is this an issue per #1 that should be fixed asap per #7, or is this fixed per #5?

Status: Fixed (was: Assigned)
Devlin, yes, since ClusterFuzz marked this issue as fixed (with a known fix range) we have nothing to do here. I assume that some of CLs in given range (388743:388749) affected the issue and fixed that.

Sorry to say the panel decided not to reward for this bug, as it was found by clusterfuzz gestures not the fuzzer itself.
