Assessing Modern Operating Systems' IPv6 Fragmentation Handling

IPv6 is the next (current?) generation Internet protocol. It has been designed to overcome many limitations of IPv4 and fix some of the issues and weaknesses. Nevertheless, IPv6 fragmentation presented many vulnerabilities similar to the IPv4 ones in the past: new testing models were presented to check the presence of such problems.

In this work, we demonstrate that IPv6 fragmentation issues are still present today in operating systems because of the weakness of the model used to test their compliance. We also propose a new model that overcomes these limitations.
