----------------------------------
Summary: [csharp] Enforce a maximum decompressed block size
Key: AVRO-4286
URL: https://issues.apache.org/jira/browse/AVRO-4286
Project: Apache Avro
Issue Type: Sub-task
Components: csharp
Affects Versions: 1.13.0
Reporter: Ismaël Mejía
{{DataFileReader.HasNext()}} in
{{lang/csharp/src/apache/main/File/DataFileReader.cs}} calls
{{_codec.Decompress(...)}}, and the codec implementations (deflate, snappy,
zstandard, bzip2, xz) decompress via {{Stream.CopyTo}} into an unbounded
{{MemoryStream}} (or a full-buffer decode) with no size limit.
Enforce a configurable maximum decompressed size in the codecs and fail
decoding with a clear error when a block would exceed it. Add a test with a
high-ratio block.
