MessagePack for Python (the `msgpack` package) has an out-of-bounds read in versions up to and including 1.2.0. If an `Unpacker` is reused after it has raised and caught an error, it can read out of bounds and crash the process with a segmentation fault. Code that streams untrusted MessagePack through a single long-lived `Unpacker` can therefore be crashed on demand, a denial-of-service risk.
