Kategori: Debian Local Security Checks Riskfaktor: High Tillagt: 1 jul 2009
Synopsis:

The remote host is missing the DSA-1823 security update

Description:

Several vulnerabilities have been discovered in Samba, a SMB/CIFS file,
print, and login server. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2009-1886
The smbclient utility contains a formatstring vulnerability where commands dealing with file names treat user input as format strings to asprintf.
CVE-2009-1888
In the smbd daemon, if a user is trying to modify an access control list (ACL) and is denied permission, this deny may be overridden if the parameter "dos filemode" is set to "yes" in the smb.conf and the user already has write access to the file. The old stable distribution (etch) is not affected by these problems. For the stable distribution (lenny), these problems have been fixed in version 3.2.5-4lenny6.
