DSA-231-1 dhcp3 -- Stack-Überläufe

Datum des Berichts:

17. Jan 2003

Betroffene Pakete:

dhcp3

Verwundbar:

Sicherheitsdatenbanken-Referenzen:

In Mitres CVE-Verzeichnis: CVE-2003-0026.
CERTs Verwundbarkeiten, Hinweise und Ereignis-Notizen: VU#284857, CA-2003-01.

Weitere Informationen:

Das Internet Software Consortium entdeckte mehrere Verwundbarkeiten bei einer Prüfung des ISC DHCP-Daemons. Die Verwundbarkeiten existieren in Fehlerbehandlungs-Routinen innerhalb der minires-Bibliothek und könnten als Stack-Überlauf ausgenutzt werden. Dies könnte es einem entfernten Angreifer erlauben, willkürlichen Code mit der Benutzerkennung auszuführen, unter der der dhcpd läuft, üblicherweise root. Andere DHCP-Server als dhcp3 dürften nicht davon betroffen sein.

Für die stable Distribution (Woody) wurde dieses Problem in Version 3.0+3.0.1rc9-2.1 behoben.

Die alte stable Distribution (Potato) enthält keine dhcp3-Pakete.

Für die unstable Distribution (Sid) wurde dieses Problem in Version 3.0+3.0.1rc11-1 behoben.

Wir empfehlen Ihnen, Ihr dhcp3-server Paket zu aktualisieren.

Behoben in:

Debian GNU/Linux 3.0 (woody)
