CVE

CVE-2012-1192

TITLE

Unbound Vulnerabilities that allow continuous name resolution for invalid domain names

Trust: 0.8

sources: JVNDB: JVNDB-2012-001508

DESCRIPTION

The 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
