Descriptions

Buffer overflow in the exif_entry_format_value function in exif-entry.c in the EXIF Tag Parsing Library (aka libexif) 0.6.20 allows remote attackers to cause a denial of service or possibly execute arbitrary code via crafted EXIF tags in an image.

Un desbordamiento de búfer en la función exif_entry_format_value en Exif-entry.c en la biblioteca de análisis de etiquetas EXIF (también conocida como libexif) v0.6.20 permite a atacantes remotos causar una denegación de servicio o posiblemente ejecutar código de su elección a través de etiquetas EXIF debidamente modificadas en una imagen.

Multiple vulnerabilities have been found in libexif and exif, some of which may allow execution of arbitrary code. Versions less than 0.6.21 are affected.
