Handling of Overlapping IPv6 Fragments
RFC 5722, “Handling of Overlapping IPv6 Fragments”, is a Proposed Standard document published in December 2009 by S. Krishnan. It updates RFC 2460. It has since been updated by RFC 6946. The canonical text is published by the RFC Editor.
Abstract
The fragmentation and reassembly algorithm specified in the base IPv6 specification allows fragments to overlap. This document demonstrates the security issues associated with allowing overlapping fragments and updates the IPv6 specification to explicitly forbid overlapping fragments. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
