utilities to facilitate DNS programming, did not correctly implement a
buffer boundary check in its RR DNS record parser. This weakness could
enable overflow of a heap buffer if a maliciously-crafted record is
parsed, potentially allowing the execution of arbitrary code. The
scope of compromise will vary with the context in which ldns is used,
and could present either a local or remote attack vector."
