03 Oct 2019 — Unbound before 1.9.4 accesses uninitialized memory, which allows remote attackers to trigger a crash via a crafted NOTIFY query. The source IP address of the query must match an access-control rule. Unbound versiones anteriores a 1.9.4, accede a la memoria no inicializada, lo que permite a atacantes remotos desencadenar un bloqueo por medio de una consulta NOTIFY diseñada. La dirección IP del origen de la consulta debe coincidir con una regla de control de acceso.

23 Jan 2018 — A flaw was found in the way unbound before 1.6.8 validated wildcard-synthesized NSEC records. An improperly validated wildcard NSEC record could be used to prove the non-existence (NXDOMAIN answer) of an existing wildcard record, or trick unbound into accepting a NODATA proof. Se ha encontrado un error en la forma en la que unbound, en versiones anteriores a la 1.6.8, validaba los registros NSEC sintetizados con caracteres comodín. Un registro con caracteres comodín NSEC validado incorrectamente podría empl... • http://www.securityfocus.com/bid/102817 • CWE-20: Improper Input Validation CWE-358: Improperly Implemented Security Check for Standard •
