Today, we released version 4.2.2 of the authoritative DNS name server NSD.
This release fixes a number of, smaller, bugs. Several failures are fixed in the zone file parser, reported by fuzzing from Frederic Cambus.
NSD now warns when a zonefile is parsed with SSHFP records in it with wrong lengths. The record itself is still managed normally, eg. does not cause the zone to stop loading. They are output into log, but the warnings are easily visible from the commandline using nsd-checkzone.
The release also fixes a segfault on exit, that originated from a fix in 4.2.1.
You can get source packages of this version from the downloads page.
