DSA-1963-1 unbound -- felaktig kryptografisk implementering

Rapporterat den:
2009-12-23
Berörda paket:
unbound
Sårbara:
Ja
Referenser i säkerhetsdatabaser:
I Mitres CVE-förteckning: CVE-2009-3602.
Ytterligare information:

Det upptäcktes att Unbound, en DNS-uppslagare, inte kontrollerar kryptografiska signaturer i NSEC3-data korrekt. Som ett resultat av detta förlorar zoner signerade med NSEC3-varianten av DNSSEC sina kryptografiska skydd. (En angripare skulle fortfarande vara tvungen att utföra ett vanligt cacheförgiftningsangrepp för att lägga in dålig data i cachen.)

Den gamla stabila utgåvan (Etch) innehåller inte något unbound-paket.

För den stabila utgåvan (Lenny) har detta problem rättats i version 1.0.2-1+lenny1.

För den instabila utgåvan (Sid) och uttestningsutgåvan (Squeeze) har detta problem rättats i version 1.3.4-1.

Vi rekommenderar att ni uppgraderar ert unbound-paket.

Rättat i:

Debian GNU/Linux 5.0 (lenny)
