> Project: Apache Avro
> Issue Type: Bug
> Components: csharp
> Reporter: Philip Sanetra
> Priority: Major
> Fix For: 1.11.0
>
>
> The BinaryDecoder.ReadString() method on NetStandard2.1+ produces an
> OutOfMemoryException if there is invalid input caused by this code:
>
> {code:c#}
> int length = ReadInt();
> Span<byte> buffer = length <= StackallocThreshold ? stackalloc byte[length] :
> (bufferArray = ArrayPool<byte>.Shared.Rent(length)).AsSpan(0,
> length);
> {code}
>
> ArrayPool<byte>.Shared.Rent(length) will cause the exception if ReadInt()
> returns a big number like int.MaxValue.
