DSA-273-1 krb4 -- kryptografisk svaghed

Rapporteret den:
28. mar 2003
Berørte pakker:
krb4
Sårbar:
Ja
Referencer i sikkerhedsdatabaser:
I Mitres CVE-ordbog: CVE-2003-0138, CVE-2003-0139.
CERTs noter om sårbarheder, bulletiner og hændelser: VU#623217, VU#442569.
Yderligere oplysninger:

En kryptografisk svaghed i version 4 af Kerberos-protokollen tillader en angriber at anvende et "chosen-plaintext"-angreb til at give sig ud for en principal i et "realm". Yderligere kryptografiske svagheder i krb4-implementationen giver mulighed for klippe-klistre-angreb til fabrikation af krb4-"tickets" til uautoriserede klient-principaler, hvis tredobbelte DES-nøgler anvendes til at fæste ("key") krb4-tjenester. Disse angreb kan undergrave et steds komplette infrastruktur til Keberos-autentifikation.

I den stabile distribution (woody) er dette problem rettet i version 1.1-8-2.3.

I den gamle stabile distribution (potato) er dette problem rettet i version 1.0-2.3.

I den ustabile distribution (sid) er dette problem rettet i version 1.2.2-1.

Vi anbefaler at du omgående opgraderer dine krb4-pakker.

Rettet i:

Debian GNU/Linux 2.2 (potato)
