Referenser i säkerhetsdatabaser:

I Mitres CVE-förteckning: CVE-2003-0138, CVE-2003-0139.
CERTs information om sårbarheter, bulletiner och incidenter: VU#623217, VU#442569.

Ytterligare information:

En kryptografisk svaghet i version 4 av Kerberosprotokollet gör det möjligt för en angripare att använda ett angrepp med ”vald rentext” (eng. chosen-plaintext attack) för att imitera valfri ”principal” i en sfär (eng. realm). Ytterligare kryptografiska svagheter i krb4-implementationen möjliggör klipp-och-klistra-angrepp för att fabrikera krb4-biljetter för oauktoriserade klient-”principals” om trippel-DES-nycklar används för att låsa krb4-tjänster. Dessa angrepp kan göra ett områdes hela Kerberosautentiseringsinfrastruktur osäker.

För den stabila utgåvan (Woody) har detta problem rättats i version 1.1-8-2.3.

För den gamla stabila utgåvan (Potato) har detta problem rättats i version 1.0-2.3.

För den instabila utgåvan (Sid) har detta problem rättats i version 1.2.2-1.

Vi rekommenderar att ni uppgraderar era krb4-paket omedelbart.
