Debian Security Advisory DSA-048-1                   security@debian.org

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.


Debian GNU/Linux 2.2 alias potato

  Potato was released for alpha, arm, i386, m68k, powerpc and sparc.
