Description:
 The mnote_olympus_entry_get_value function in olympus/mnote-olympus-entry.c
 in the EXIF Tag Parsing Library (aka libexif) before 0.6.21 allows remote
 attackers to cause a denial of service (divide-by-zero error) via an image
 with crafted EXIF tags that are not properly handled during the formatting
 of EXIF maker note tags.
