(ImageMagick: Multiple vulnerabilities)

    regenrecht reported multiple infinite loops in functions ReadDCMImage()
    and ReadXCFImage() (CVE-2007-4985), multiple integer overflows when
    handling certain types of images (CVE-2007-4986, CVE-2007-4988), and an
    off-by-one error in the ReadBlobString() function (CVE-2007-4987).
  
Impact :

    A remote attacker could entice a user to open a specially crafted
    image, possibly resulting in the remote execution of arbitrary code
    with the privileges of the user running the application, or an
    excessive CPU consumption. Note that applications relying on
    ImageMagick to process images can also trigger the vulnerability.
  
Workaround :

    There is no known workaround at this time."
