Descriptions

Integer overflow in the exif_process_IFD_TAG function in exif.c in the exif extension in PHP 5.4.0beta2 on 32-bit platforms allows remote attackers to read the contents of arbitrary memory locations or cause a denial of service via a crafted offset_val value in an EXIF header in a JPEG file, a different vulnerability than CVE-2011-0708.

Un desbordamiento de entero en la función exif_process_IFD_TAG en el fichero exif.c de la extensión exif de PHP v5.4.0 beta2 en las plataformas de 32 bits permite a atacantes remotos leer los contenidos de ubicaciones de memoria aleatorias o causar una denegación de servicio a través de un valor de offset_val concreto en una cabecera EXIF en un archivo JPEG. Se trata de una vulnerabilidad diferente a CVE-2.011-0708.
