Ytterligare information:

Flera sårbarheter har upptäckts i Samba, en fil-, skrivar och loginserver för SMB/CIFS. Projektet Common Vulnerabilities and Exposures identifierar följande problem:

CVE-2009-1886
smbclient-verktyget innehåller en formatsträngssårbarhet där kommandon som hanterar filnamn behandlar användarindata som formatsträngar till asprintf.
CVE-2009-1888
I smbd-servern kan, om en användare försöker ändra en åtkomstkontrollista (Access Control List, ACL) och nekas åtkomst, detta nekande kringgås om parametern "dos filemode" är satt till "yes" i smb.conf och användaren redan har skrivåtkomst till filen.

Den gamla stabila utgåvan (Etch) påverkas inte av dessa problem.

För den stabila utgåvan (Lenny) har dessa problem rättats i version 3.2.5-4lenny6.

Den instabila utgåvan (Sid), som bara berörs av CVE-2009-1888, kommer rättas till inom kort.

Vi rekommenderar att ni uppgraderar ert samba-paket.
