Doc Text:
A flaw was found in Ghostscript. The`pdf_base_font_alloc` function used by the `pdfwrite` device will use a hexadecimal pointer representation for the constructed BaseFont name if the input name is empty. This flaw allows an attacker to obtain this pointer value by reading back to the output file after writing to a temporary writable and readable location.
