-
Sebastian Krahmer från SuSE:s säkerhetsrevideringsgrupp hittade två problem i samba, en populär implementation av SMB/CIFS. Problemen är:
- ett buffertspill i koden som sammanfogar fragmenterade SMB/CIFS-paket i smbd. Eftersom smbd körs som root kan en angripare använda detta för att få rootbehörighet på en maskin som kör smbd.
- koden som skriver reg-filer var sårbar för en chown-kapplöpning som gjorde det möjligt för en lokal användare att skriva över systemfiler
Båda problemen har rättats i uppströmsversion 2.2.8, samt version 2.2.3a-12.1 av paketen för Debian GNU/Linux 3.0/Woody.
