DSA-731-1 krb4 -- Pufferüberläufe

Datum des Berichts:

02. Jun 2005

Betroffene Pakete:

Verwundbar:

Sicherheitsdatenbanken-Referenzen:

In Mitres CVE-Verzeichnis: CVE-2005-0468, CVE-2005-0469.
CERTs Verwundbarkeiten, Hinweise und Ereignis-Notizen: VU#341908, VU#291924.

Weitere Informationen:

In telnet-Clients wurden mehrere Probleme entdeckt, die von böswilligen Daemons bei der Verbindung mit den Clients ausgenutzt werden können. Das »Common Vulnerabilities and Exposures project« legt die folgenden Probleme fest:

CAN-2005-0468
Gaël Delalleau entdeckte einen Pufferüberlauf in der Funktion env_opt_add(), der es einem entfernten Angreifer erlaubt, beliebigen Code auszuführen.
CAN-2005-0469
Gaël Delalleau entdeckte einen Pufferüberlauf in der Behandlung von LINEMODE-Unteroptionen in telnet-Clients. Dies kann bei der Verbindung mit einem böswilligen Server die Ausführung von beliebigem Code zur Folge haben.

Für die Stable-Distribution (Woody) wurden diese Probleme in Version 1.1-8-2.4 behoben.

Für die Testing-Distribution (Sarge) wurden diese Probleme in Version 1.2.2-11.2 behoben.

Für die Unstable-Distribution (Sid) wurden diese Probleme in Version 1.2.2-11.2 behoben.

Wir empfehlen Ihnen, Ihre krb4-Pakete zu aktualisieren.
