Debian: DSA-1823-2 Moderate: Samba User Privilege Issues

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.
