Yderligere oplysninger:

Sebastian Krahmer fra SuSEs sikkerhedskontrolteam har fundet to problemer i samba, en populær SMB/CIFS-implementering. Problemerne er:

  • Et bufferoverløb i koden til gendannelse af SMB/CIFS-pakkefragmenter som anvendes af smbd. Da smbd kører som root, kan en angriber benytte dette til at få root-adgang til en maskine som kører smbd.
  • Koden til at skrive reg-filer var sårbar overfor et "chown race", hvilket gjorde det muligt for en lokal bruger at overskrive systemfiler.

Begge problemer er rettet i opstrøms version 2.2.8 og i version 2.2.3a-12.1 af pakkerne i Debian GNU/Linux 3.0/woody.

Rettet i:

Debian GNU/Linux 3.0 (woody)
