DSA-273-1 krb4 -- Kryptographische Schwachstelle

Datum des Berichts:

28. Mär 2003

Verwundbar:

Sicherheitsdatenbanken-Referenzen:

In Mitres CVE-Verzeichnis: CVE-2003-0138, CVE-2003-0139.
CERTs Verwundbarkeiten, Hinweise und Ereignis-Notizen: VU#623217, VU#442569.

Weitere Informationen:

Eine kryptographische Schwachstelle in Version 4 des Kerberos Protokolls erlaubt einem Angreifer einen Angriff mit einem gewählten Klartext zur Nachahmung eines beliebigen Prinzipals in einem Realm. Zusätzliche kryptographische Schwachstellen in der krb4-Implementation, die in der MIT krb5 Distribution enthalten ist, erlauben die Benutzung von Ausschneiden-und-Einfügen-Angriffen, um für unberechtigte Client-Prinzipale krb4-Tickets herzustellen, falls Triple-DES Schlüssel benutzt werden, um krb4-Dienste freizuschalten. Diese Angriffe können die gesamte Kerberos-Infrastruktur einer Site untergraben.

Für die stable Distribution (Woody) wurde dieses Problem in Version 1.1-8-2.3 behoben.

Für die alte stable Distribution (Potato) wurde dieses Problem in Version 1.0-2.3 behoben.

Für die unstable Distribution (Sid) wurde dieses Problem in Version 1.2.2-1 behoben.

Wir empfehlen Ihnen, Ihr krb4-Paket unverzüglich zu aktualisieren.
