How to fix?

Overview

Affected versions of this package are vulnerable to Out-of-bounds Read in the 6LoWPAN implementation which can cast a UDP header structure at a certain offset in a packet buffer. This is exploitable because the code does not check whether the packet buffer is large enough to fit a full UDP header structure from the offset where the casting is made.

Note: This vulnerability affects anyone running devices that may receive 6LoWPAN packets from external parties.
