CVE-2012-1192 (CCN-73358)

Assigned:2012-02-17
Published:2012-02-17
Updated:2012-02-20
Summary: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.
