FKIE_CVE-2012-1192

Vulnerability from fkie_nvd - Published: 2012-02-17 22:55 - Updated: 2026-04-29 01:13
Severity
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.
