Descriptions

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.

La función mnote_olympus_entry_get_value en Olympus/mNote-olympus-entry.c en la biblioteca de análisis de etiquetas EXIF (también conocido como libexif) antes de v0.6.21 permite a atacantes remotos causar una denegación de servicio (división por error cero) a través de una imagen con etiquetas EXIF modificadas que no se manejan correctamente durante el formateo de etiquetas de notas EXIF.
