"Jan-Piet Mens discovered that the BIND DNS server would crash when
processing an invalid DNSSEC key rollover, either due to an error on
the zone operator's part, or due to interference with network traffic
by an attacker. This issue affects configurations with the directives
'dnssec-validation auto;' (as enabled in the Debian default
configuration) or 'dnssec-lookaside auto;'.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
