TL;DR

serde_yaml_bw did not consider limitation in processing long sequences of user-crafted YAML files. While this does not directly lead to a crash, it may consume excessive memory to process this input. This has the potential of a denial-of-service attack if multiple large sequences are processed at the same time.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range.
