Package: libnetpbm10 Version: 2:10.0-11 Severity: normal
If pnmtotiff is run on a very wide ppm image, it creates creates images with a tiff tag "RowsPerStripe" equal to zero, which is clearly invalid. To reproduce, create a (possibly empty) image with gimp that is wider than 3000 pixels, run pnmtotiff on it. libtiff will create a warning. *Some* programs might still be able to load this image. The bug is in pnmtotiff.c, function computeRasterParm, line 598, where the number of rows per stripe is computed as follows: *rowsperstripP = (8 * 1024) / *bytesperrowP; For overlong lines, this results in the zero value. Suggestion: Change lines 597ff to: if (requested_rowsperstrip == -1 ) { *rowsperstripP = (8 * 1024) / *bytesperrowP; if (*rowsperstripP == 0) *rowsperstripP = 1; } else { *rowsperstripP = requested_rowsperstrip; } Regards, Thomas Richter -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
