    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:
        It was discovered a buffer overflow in libpng which allows remote
        attackers to execute arbitrary code via a PNG image that triggers 
        an additional data row.
        It was discovered a memory leak in libpng which allows remote
        attackers to cause a denial of service (memory consumption and
        application crash) via a PNG image containing malformed Physical
        Scale (aka sCAL) chunks
    For the stable distribution (lenny), these problems have been fixed in
    version 1.2.27-2+lenny4.
    For the testing (squeeze) and unstable (sid) distribution, these
    problems have been fixed in version 1.2.44-1
    We recommend that you upgrade your libpng package.
