Weitere Informationen:

Sebastian Krahmer vom SuSE-Sicherheits-Test-Team entdeckte zwei Probleme in samba, einer beliebten SMB/CIFS-Implementierung. Die Probleme sind:

Ein Pufferüberlauf im SMB/CIFS Zusammenführungs-Code für Paket-Fragmente, der von smbd verwendet wird. Da smbd als root läuft, kann ein Angreifer dies dazu verwenden, root-Zugriff auf eine Maschine zu erlangen, auf der smbd läuft.
Der Code, um reg-Dateien zu schreiben, war für eine chown-Ausführungs-Verwundbarkeit anfällig, die es einem lokalen Benutzer ermöglicht, System-Dateien zu überschreiben.

Beide Probleme wurden upstream in Version 2.2.8 behoben, und in Version 2.2.3a-12.1 des Pakets für Debian GNU/Linux 3.0 (Woody).

Behoben in:

Debian GNU/Linux 3.0 (woody)
