Descriptions

libexif through 0.6.21 is vulnerable to out-of-bounds heap read vulnerability in exif_data_save_data_entry function in libexif/exif-data.c caused by improper length computation of the allocated data of an ExifMnote entry which can cause denial-of-service or possibly information disclosure.

libexif hasta la versión 0.6.21 es vulnerable a una lectura de la memoria dinámica (heap) fuera de límites en la función exif_data_save_data_entry en libexif/exif-data.c. Esto se debe al cálculo incorrecto de la longitud de los datos asignados de una entrada ExifMnote que podrían provocar una denegación de servicio o, posiblemente, una divulgación de información.

Liu Bingchang discovered that libexif incorrectly handled certain files. An attacker could possibly use this issue to access sensitive information or cause a denial of service. This issue only affected Ubuntu 12.04 ESM, Ubuntu 14.04 ESM and Ubuntu 16.04 LTS. Lili Xu and Bingchang Liu discovered that libexif incorrectly handled certain files.
