Debian 2.2 DSA-048-1 Moderate: Samba Symlink Attack Security Update

Debian Security Advisory DSA-048-1 addresses a moderate Samba symlink attack due to unsafe temporary file creation.
samba sometimes does not create temporary files safely which may result in a symlink attack.

Summary

Package : samba
Problem type : symlink attack
Debian-specific: no

Marcus Meissner discovered that samba was not creating temporary
files safely in two places:

* when a remote user queried a printer queue samba would creates a
temporary file in which the queue data would be written. This was
doing using a predictable filename and insecurely, allowing a local
attacker to trick samba into overwriting arbitrary files.
* smbclient "more" and "mput" commands also creates temporary files
in /tmp insecurely.

Both problems have been fixed in version 2.0.7-3.2. and we recommand
that you upgrade your samba package immediately.

wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.
