https://notcve.org/view.php?id=CVE-2011-4528

Unbound before 1.4.13p2 attempts to free unallocated memory during processing of duplicate CNAME records in a signed zone, which allows remote DNS servers to cause a denial of service (daemon crash) via a crafted response. Unbound antes de v1.4.13p2 intenta liberar memoria sin asignar durante el procesado de registros CNAME duplicados, lo que permite a servidores DNS remotos provocar una denegación de servicio (caída del demonio) a través de una respuesta modificada. • http://lists.fedoraproject.org/pipermail/package-announce/2012-January/071525.html http://lists.fedoraproject.org/pipermail/package-announce/2012-January/071535.html http://osvdb.org/77909 http://secunia.com/advisories/47326 http://unbound.nlnetlabs.nl/downloads/CVE-2011-4528.txt http://www.debian.org/security/2011/dsa-2370 http://www.kb.cert.org/vuls/id/209659 • CWE-399: Resource Management Errors •
