    Jason Molenda and Hiromitsu Takagi found ways to exploit cross site
    scripting bugs in mhonarc, a mail to HTML converter.  When processing
    maliciously crafted mails of type text/html, mhonarc, does not
    deactivate all scripting parts properly.  This is fixed in upstream
    version 2.5.3.
    
    If you are worried about security, it is recommended that you disable
    support of text/html messages in your mail archives.  There is no
    guarantee that the mhtxthtml.pl library is robust enough to eliminate
    all possible exploits that can occur with HTML data.
    
    To exclude HTML data, you can use the MIMEEXCS resource.  For example:
    
        
    text/html
        text/x-html
        
    
    The use of "text/x-html" is probably not used any more, but is good to
    include it, just-in-case.
    
    If you are concerend that this could block out the entire contents of
    some messages, then you could do the following instead:
    
        
    text/html; m2h_text_plain::filter; mhtxtplain.pl
        text/x-html; m2h_text_plain::filter; mhtxtplain.pl
        
    
    This treats the HTML as text/plain.
    
    The above problems have been fixed in version 2.5.2-1.1 for the
    current stable stable distribution (woody), in version 2.4.4-1.1 for
    the old stable distribution (potato) and in version 2.5.11-1 for the
    unstable distribution (sid).
    
    We recommend that you upgrade your mhonarc packages.
    
    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.
