Descriptions

When PHP EXIF extension is parsing EXIF information from an image, e.g. via exif_read_data() function, in PHP versions 7.1.x below 7.1.31, 7.2.x below 7.2.21 and 7.3.x below 7.3.8 it is possible to supply it with data what will cause it to read past the allocated buffer. This may lead to information disclosure or crash.

Cuando la extensión EXIF de PHP está analizando información EXIF de una imagen, p.ej. por medio de la función exif_read_data(), en PHP versiones 7.1.x anteriores a 7.1.31, versiones 7.2.x anteriores a 7.2.21 y versiones 7.3.x anteriores a 7.3.8, es posible suministrarle datos que causará que se lea más allá del búfer asignado. Esto puede conllevar a la divulgación de información o bloqueo.
