(exiftags: Multiple vulnerabilities)

    Meder Kydyraliev (Google Security) discovered that Exif metadata is not
    properly sanitized before being processed, resulting in illegal memory
    access in the postprop() and other functions (CVE-2007-6354). He also
    discovered integer overflow vulnerabilities in the parsetag() and other
    functions (CVE-2007-6355) and an infinite recursion in the readifds()
    function caused by recursive IFD references (CVE-2007-6356).
  
Impact :

    An attacker could entice the user of an application making use of
    exiftags or an application included in exiftags 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."
