DSA-409-1 bind -- lammelesangreb

Rapporteret den:
5. jan 2004
Berørte pakker:
bind
Sårbar:
Ja
Referencer i sikkerhedsdatabaser:
I Bugtraq-databasen (hos SecurityFocus): BugTraq-id 9114.
I Mitres CVE-ordbog: CVE-2003-0914.
CERTs noter om sårbarheder, bulletiner og hændelser: VU#734644.
Yderligere oplysninger:

En sårbarhed er opdaget i BIND, en domænenavnsserver, hvorved en ondsindet navneserver kunne returnere autoritative negative svar med store TTL-værdier (time-to-live - levetid) og dermed gøre et domænenavn utilgængeligt. Et succesrigt angreb ville kræve at en sårbar BIND-instans sender en forespørgsel til en ondsindet navneserver.

Pakken bind9 er ikke påvirket af denne sårbarhed.

I den nuværende stabile distribution (woody) er dette problem rettet i version 1:8.3.3-2.0woody2.

I den ustabile distribution (sid) er dette problem rettet i version 1:8.4.3-1.

Vi anbefaler at du opdaterer din bind-pakke.

Rettet i:

Debian GNU/Linux 3.0 (woody)
