VAR-201202-0179
Vulnerability from variot - Updated: 2023-12-18 11:26The resolver in Unbound before 1.4.11 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. Unbound is an open source recursive DNS server software. A vulnerability exists in the resolver in versions prior to Unbound 1.4.11. Unbound is prone to a remote security vulnerability
