Descriptions

The exif_process_TIFF_in_JPEG function in ext/exif/exif.c in PHP before 5.5.35, 5.6.x before 5.6.21, and 7.x before 7.0.6 does not validate TIFF start data, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via crafted header data.

La función exif_process_TIFF_in_JPEG en ext/exif/exif.c en PHP en versiones anteriores a 5.5.35, 5.6.x en versiones anteriores a 5.6.21 y 7.x en versiones anteriores a 7.0.6 no valida los datos de inicio TIFF, lo que permite a atacantes remotos provocar una denegación de servicio (lectura fuera de límites) o posiblemente tener otro impacto no especificado a través de datos de cabecera manipulados.

It was discovered that the PHP Fileinfo component incorrectly handled certain magic files. An attacker could use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 16.04 LTS.
