MessagePack: Nested arrays can blow past buffer length limits

Impact MessagePack-CSharp is vulnerable to denial of service through excessive memory allocation when deserializing attacker-controlled data into System.Object. When PrimitiveObjectFormatter encounters an array, it allocates an object using the declared array length before enforcing the configure...
