Description

Fix denial of service attack when processing NSEC3-signed zone queries, fixed by not calling memcpy with overlapping ranges in bin/named/query.c. - patch backported from 9.8.6-P2 by Marc Deslauriers from the Ubuntu Security team for USN-2081-1.

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.
