    Several vulnerabilities have been discovered in libpng, a library for
    reading and writing PNG files. The Common Vulnerabilities and
    Exposures project identifies the following problems:
    
    CVE-2009-2042
    
    libpng does not properly parse 1-bit interlaced images with width values
    that are not divisible by 8, which causes libpng to include
    uninitialized bits in certain rows of a PNG file and might allow remote
    attackers to read portions of sensitive memory via "out-of-bounds
    pixels" in the file.
    
    
    CVE-2010-0205
    
    libpng does not properly handle compressed ancillary-chunk data that has
    a disproportionately large uncompressed representation, which allows
    remote attackers to cause a denial of service (memory and CPU
    consumption, and  application hang) via a crafted PNG file
    
    
    For the stable distribution (lenny), these problems have been fixed in
    version 1.2.27-2+lenny3.
    
    For the testing (squeeze) and unstable (sid) distribution, these
    problems have been fixed in version 1.2.43-1
    
    We recommend that you upgrade your libpng package.
    
    Upgrade instructions
    - --------------------
    
    wget url

    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
