How to fix?

There is no fixed version for adamdunkels/uip.

Overview

Affected versions of this package are vulnerable to Out-of-bounds Read. The code that processes DNS responses in uIP through 1.0, as used in Contiki and Contiki-NG, does not check whether the number of responses specified in the DNS packet header corresponds to the response data available in the DNS packet, leading to an out-of-bounds read and Denial-of-Service in resolv.c.
