### Description

The resolver in dnscache in Daniel J. Bernstein djbdns 1.05 overwrites cached server names and TTL values in NS records during the processing of a response to an A record query, which allows remote attackers to trigger continued resolvability of revoked domain names via a "ghost domain names" attack.
