Descriptions

When processing certain files, PHP EXIF extension in versions 7.1.x below 7.1.28, 7.2.x below 7.2.17 and 7.3.x below 7.3.4 can be caused to read past allocated buffer in exif_process_IFD_TAG function. This may lead to information disclosure or crash.

Al procesar ciertos archivos, la extensión PHP EXIF en las versiones 7.1.x anteriores a la 7.1.28, 7.2.x anteriores a la 7.2.17 y 7.3.x anteriores a la 7.3.4 puede hacer que se lea el buffer asignado en la función exif_process_IFD_TAG. Esto puede conducir a la revelación de información o a un cierre inesperado.
