    Package        : fetchmail
    Problem type   : buffer overflow
    Debian-specific: no
    
    Wolfram Kleff found a problem in fetchmail: it would crash when
    processing emails with extremely long headers. The problem was
    a buffer overflow in the header parser which could be exploited.
    
    This has been fixed in version 5.3.3-1.3, and we recommend that
    you upgrade your fetchmail 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.
