Descriptions

Buffer overflow in the LWZReadByte_ function in ext/gd/libgd/gd_gif_in.c in the GD extension in PHP before 5.1.5 allows remote attackers to have an unknown impact via a GIF file with input_code_size greater than MAX_LWZ_BITS, which triggers an overflow when initializing the table array.

Desbordamiento de búfer en la función LWZReadByte_ en ext/gd/libgd/gd_gif_in.c en la extensión GD en PHP anterior a 5.1.5 permite a atacantes remotos tener un impacto desconocido mediante un fichero GIF con input_code_size mayor que MAX_LWZ_BITS, lo cual dispara un desbordamiento al inicializar el array tabla.

The file_exists and imap_reopen functions in PHP before version 5.1.5 do not check for the safe_mode and open_basedir settings, which allows local users to bypass the settings. A buffer overflow in the LWZReadByte function in ext/gd/libgd/gd_gif_in.c in the GD extension in PHP before version 5.1.5 allows remote attackers to have an unknown impact via a GIF file with input_code_size greater than MAX_LWZ_BITS, which triggers an overflow when initializing the table array.
