CVE-2020-19860:

When ldns version 1.7.1 verifies a zone file, the ldns_rr_new_frm_str_internal function has a heap out of bounds read vulnerability. An attacker can leak information on the heap by constructing a zone file payload.

Patch: https://github.com/NLnetLabs/ldns/commit/15d96206996bea969fbc918eb0a4a346f514b9f3
