> Project: Cassandra

> Components: Messaging/Client
> Reporter: Jon Meredith

> Priority: Normal
> Fix For: 4.0.x, 4.1.x, 5.0

>
> When deserializing collections sent from the client, if an element in the
> collection is incorrectly serialized, Collections.getValue can return null if
> the length of the element is negative. Currently this isn't detected and
> serialization continues, calling validate and throwing an NPE in serializers
> that don't handle null value buffers.
> Detect the malformed input and throw a better MarshalException so it will be
> converted to an InvalidRequestException for the client.
