    Package        : xtel
    Problem type   : symlink attack
    Debian-specific: no
    
    The xtel (a X emulator for minitel) package as distributed with Debian
    GNU/Linux 2.2 has two possible symlink attacks:
    
    * xteld creates a temporary file /tmp/.xtel- without checking
      for symlinks.
    * when printing a hardcope xtel would create a temporary file without
      protecting itself against symlink attacks.
    
    Both problems have been fixed in version 3.2.1-4.potato.1 .
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
