    Package        : libpng2, libpng3
    Vulnerability  : buffer overflow
    Problem-Type   : remote
    Debian-specific: no
    
    Developers of the PNG library have fixed a buffer overflow in the
    progressive reader when the PNG datastream contains more IDAT data
    than indicated by the IHDR chunk.  Such deliberately malformed
    datastreams would crash applications which could potentially allow an
    attacker to execute malicious code.  Programs such as Galeon,
    Konquerer and various others make use of these libraries.
    
    To find out which packages depend on this library, you may want to
    execute the following commands:
    
        apt-cache showpkg libpng2
        apt-cache showpkg libpng3
    
    This problem has been fixed in version 1.0.12-3.woody.1 of libpng and
    version 1.2.1-1.1.woody.1 of libpng3 for the current stable
    distribution (woody) and in version 1.0.12-4 of libpng and version
    1.2.1-2 of libpng3 for the unstable distribution (sid).
    
    We recommend that you upgrade your libpng packages immediately and
    restart programs and daemons that link to these libraries and read
    external data, such as web browsers.
    
    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.

    The potato release of Debian does not seem to be vulnerable.
