  A heap-based out-of-bounds array read in the exif_entry_get_value
  function in libexif/exif-entry.c in libexif 0.6.20 and earlier allows
  remote attackers to cause a denial of service or possibly obtain
  potentially sensitive information from process memory via an image
  with crafted EXIF tags (CVE-2012-2812).

  A heap-based out-of-bounds array read in the exif_convert_utf16_to_utf8
  function in libexif/exif-entry.c in libexif 0.6.20 and earlier allows
  remote attackers to cause a denial of service or possibly obtain
  potentially sensitive information from process memory via an image
  with crafted EXIF tags (CVE-2012-2813).

  A buffer overflow in the exif_entry_format_value function in
  libexif/exif-entry.c in libexif 0.6.20 allows remote attackers to
  cause a denial of service or possibly execute arbitrary code via an
  image with crafted EXIF tags (CVE-2012-2814).

  A heap-based out-of-bounds array read in the exif_data_load_data
  function in libexif 0.6.20 and earlier allows remote attackers to
  cause a denial of service or possibly obtain potentially sensitive
  information from process memory via an image with crafted EXIF tags
  (CVE-2012-2836).

  A divide-by-zero error in the mnote_olympus_entry_get_value function
  while formatting EXIF maker note tags in libexif 0.6.20 and earlier
  allows remote attackers to cause a denial of service via an image
  with crafted EXIF tags (CVE-2012-2837).

  An off-by-one error in the exif_convert_utf16_to_utf8 function in
  libexif/exif-entry.c in libexif 0.6.20 and earlier allows remote
  attackers to cause a denial of service or possibly execute arbitrary
  code via an image with crafted EXIF tags (CVE-2012-2840).

  An integer underflow in the exif_entry_get_value function can cause a
  heap overflow and potentially arbitrary code execution while formatting
  an EXIF tag, if the function is called with a buffer size parameter
  equal to zero or one (CVE-2012-2841).

  The updated packages have been upgraded to the 0.6.21 version which
  is not vulnerable to these issues.");
