(libexif: Multiple vulnerabilities)

    Meder Kydyraliev (Google Security) discovered an integer overflow
    vulnerability in the exif_data_load_data_thumbnail() function leading
    to a memory corruption (CVE-2007-6352) and an infinite recursion in the
    exif_loader_write() function (CVE-2007-6351).
  
Impact :

    An attacker could entice the user of an application making use of
    libexif to load an image file with specially crafted Exif tags,
    possibly resulting in the execution of arbitrary code with the
    privileges of the user running the application or a Denial of Service.
  
Workaround :

    There is no known workaround at this time."
