Description filip ambroz 2022-01-10 18:03:07 UTC 
An issue in protobuf-java allowed the interleaving of com.google.protobuf.UnknownFieldSet fields in such a way that would be processed out of order. A small malicious payload can occupy the parser for several minutes by creating large numbers of short-lived objects that cause frequent, repeated pauses.

I am working on it.
3.16.1 will be skipped. 3.16.* will be deleted soon.
Some reverse dependencies depend on <3.19, so 3.18.2 will be added too.

Why?

Test case was closed as invalid and the bug marked as reproducible, so I guess this is invalid.
