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.

The unstable distribution (sid), which is only affected by CVE-2009-1888, will be fixed soon.

We recommend that you upgrade your samba package.");
