Yderligere oplysninger:

Flere fjernudnytbare sårbarheder er opdaget i BIND, en implementering af DNS-protokolsuiten. Projektet Common Vulnerabilities and Exposures har registreret følgende problemer:

CVE-2010-3762
Når DNSSEC-validering var aktiveret, håndterede BIND ikke på korrekt vis visse dårlige signaturer if multiple trust anchors fandtes til en enkelt zone, hvilket gjorde det muligt for fjernangribere at forårsage et lammelsesangreb (servernedbrud) via en DNS-forespørgsel.
CVE-2010-3614
BIND afgjorde ikke på korrekt vis sikkerhedsstatussen på en NS RRset under en DNSKEY-algoritmerollover, hvilket måske kunne føre til en zoneutilgængelighed under rollovers.
CVE-2010-3613
BIND håndterede ikke på korrektvis kombinationen af signerede negative svar og tilhørende RRSIG-poster i cachen, hvilket gjorde det muligt for fjernangribere at forårsage et lammelsesangreb (servernedbrud) via en forespørgsel efter cachede data.

Desuden forbedrer denne sikkerhedsopdatering kompatibiliteten med tidligere installerede versioner af bind9-pakken. Som en følge deraf, er det nødvendigt at iværksætte opdateringen med apt-get dist-upgrade i stedet for apt-get update.

I den stabile distribution (lenny), er disse problemer rettet i version 1:9.6.ESV.R3+dfsg-0+lenny1.

I den kommende stabile distribution (squeeze) og i den ustable distribution (sid), er disse problemer rettet i version 1:9.7.2.dfsg.P3-1.

Vi anbefaler at du opgraderer dine bind9-pakker.

Rettet i:

Debian GNU/Linux 5.0 (lenny)
