    A set of buffer overflow problems have been found in hanterm, a Hangul
    terminal for X11 derived from xterm, that will read and display Korean
    characters in its terminal window.  The font handling code in hanterm
    uses hard limited string variables but didn't check for boundaries.
    
    This problem can be exploited by a malicious user to gain access to
    the utmp group which is able to write the wtmp and utmp files.  These
    files record login and logout activities.
    
    This problem has been fixed in version 3.3.1p17-5.2 for the stable
    Debian distribution.  A fixed package for the current testing/unstable
    distribution is not yet available but will have a version number
    higher than 3.3.1p18-6.1.
    
    We recommend that you upgrade your hanterm packages immediately if you
    have them installed.  Known exploits are already available.
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
    
    If you are using the apt-get package manager, use the line for
    sources.list as given below:
    
    apt-get update
            will update the internal database
    apt-get upgrade
            will install corrected packages
    
    You may use an automated update by adding the resources from the
    footer to the proper configuration.
