-Subject: [PATCH] pdfwrite - Guard against trying to output an infinite number
-
-Bug #699255 " Buffer overflow on pprintg1 due to mishandle postscript file data to pdf"
-
-The file uses an enormous parameter to xyxhow, causing an overflow in
-the calculation of text positioning (value > 1e39).
-
-Since this is basically a nonsense value, and PostScript only supports
-real values up to 1e38, this patch follows the same approach as for
-a degenerate CTM, and treats it as 0.
-
-Adobe Acrobat Distiller throws a limitcheck error, so we could do that
-instead if this approach proves to be a problem.
