-----------------------------------------
Summary: IndexOutOfBoundsException in Paging State Version
Inference (V3 State Received on V4 Connection)
Key: CASSANDRA-17840
URL: https://issues.apache.org/jira/browse/CASSANDRA-17840
Project: Cassandra
Issue Type: Bug
Components: Messaging/Client
Reporter: Josh McKenzie
Assignee: Josh McKenzie
In {{PagingState.java}}, {{index}} is an integer field, and we add long values
to it without a {{Math.toIntExact}} check. While we’re checking for negative
return values returned by {{getUnsignedVInt}}, there's a chance that the value
returned by it is so large that addition operation would cause integer
overflow, or the value itself is large enough to cause overflow.
