Descriptions

Integer underflow in the exif_entry_get_value function in exif-entry.c in the EXIF Tag Parsing Library (aka libexif) 0.6.20 might allow remote attackers to execute arbitrary code via vectors involving a crafted buffer-size parameter during the formatting of an EXIF tag, leading to a heap-based buffer overflow.

Un desbordamiento de enteros en la función exif_entry_get_value en Exif-entry.c en la biblioteca EXIF Tag Parsing Library (también conocida como libexif) v0.6.20 podría permitir a atacantes remotos ejecutar código de su elección a través de vectores relacionados con parámetro "buffer-size" modificado a mano durante el formateo de una etiqueta EXIF, dando lugar a un desbordamiento de búfer basado en memoria dinámica (heap).
