Descriptions

The exif_process_IFD_TAG 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 properly construct spprintf arguments, 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_IFD_TAG 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 construye adecuadamente argumentos spprintf, 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.
