CVE ID : CVE-2014-0591
Debian Bug : 735190

Jared Mauch reported a denial of service flaw in the way BIND, a DNS
server, handled queries for NSEC3-signed zones. A remote attacker could
use this flaw against an authoritative name server that served
NCES3-signed zones by sending a specially crafted query, which, when
processed, would cause named to crash.
