    Package        : wwwoffle
    Vulnerability  : improper input handling
    Problem-Type   : local
    Debian-specific: no
    CVE Id         : CAN-2002-0818
    
    A problem with wwwoffle has been discovered.  The web proxy didn't
    handle input data with negative Content-Length settings properly which
    causes the processing child to crash.  It is at this time not obvious
    how this can lead to an exploitable vulnerability; however, it's better
    to be safe than sorry, so here's an update.
    
    Additionally, in the woody version empty passwords will be treated as
    wrong when trying to authenticate.  In the woody version we also
    replaced CanonicaliseHost() with the latest routine from 2.7d, offered
    by upstream.  This stops bad IPv6 format IP addresses in URLs from
    causing problems (memory overwriting, potential exploits).
    
    This problem has been fixed in version 2.5c-10.4 for the old stable
    distribution (potato), in version 2.7a-1.2 for the current stable
    distribution (woody) and in version 2.7d-1 for the unstable
    distribution (sid).
    
    We recommend that you upgrade your wwwoffle 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.
