Referencer i sikkerhedsdatabaser:

I Debians fejlsporingssystem: Fejl 348826.
I Bugtraq-databasen (hos SecurityFocus): BugTraq-id 16431.
I Mitres CVE-ordbog: CVE-2006-0351.

Yderligere oplysninger:

NISCC rapporterer at MyDNS, en DNS-server som anvender en SQL-database til lagring af data, kan snydes ind i en uendelig løkke af en fjernangriber og dermed forårsage et lammelsesangreb (denial of service).

Den gamle stabile distribution (woody) indeholder ikke mydns-pakker.

I den stabile distribution (sarge) er dette problem rettet i version 1.0.0-4sarge1.

I den ustabile distribution (sid) er dette problem rettet i version 1.1.0+pre-3.

Vi anbefaler at du opgraderer din mydns-pakke.

Rettet i:

Debian GNU/Linux 3.1 (sarge)
