Description

minio developer report:

This is a security issue because it enables MITM modification of

request bodies that are meant to have integrity guaranteed by chunk

signatures.

In a PUT request using aws-chunked encoding, MinIO ordinarily

verifies signatures at the end of a chunk. This check can be skipped

if the client sends a false chunk size that is much greater than the

actual data sent: the server accepts and completes the request

without ever reaching the end of the chunk + thereby without ever

checking the chunk signature.
