Prior to 2.5.301 and 3.1.7, MessagePack-CSharp&#39;s multi-dimensional array formatters read dimension lengths directly from the payload and allocate T[,], T[,,], or T[,,,] before validating that the dimension product matches the encoded element count. The formatter reads a guarded element array header, but allocation of the target multi-dimensional array happens before the dimensions are checked against that element count. A small payload can therefore declare large dimensions, provide an empty or tiny inner array, and cause a large heap allocation before element data is validated. This vulnerability is fixed in 2.5.301 and 3.1.7.</p> <p><strong>Affected:</strong> MessagePack-CSharp</p> <p>MessagePack for C# is a MessagePack serializer for C#.
