    Package        : netkit-telnet
    Problem type   : remote exploit
    Debian-specific: no
    
    The telnet daemon contained in the netkit-telnet_0.16-4potato1 package in
    the 'stable' (potato) distribution of Debian GNU/Linux is vulnerable to an
    exploitable overflow in its output handling.
    The original bug was found by <This email address is being protected from spambots. You need JavaScript enabled to view it.>, and announced to
    bugtraq on Jul 18 2001. At that time, netkit-telnet versions after 0.14 were
    not believed to be vulnerable.
    On Aug 10 2001, zen-parse posted an advisory based on the same problem, for
    all netkit-telnet versions below 0.17.
    More details can be found on  https://www.securityfocus.com/archive/1/203000 .
    As Debian uses the 'telnetd' user to run in.telnetd, this is not a remote
    root compromise on Debian systems; the 'telnetd' user can be compromised.
    
    We strongly advise you update your netkit-telnet packages to the versions
    listed below.
    
    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.
