CVE-2010-1411 was not complete. * libtiff/tiffiop.h (TIFFSafeMultiply): New macro to safely multiply two integers. Returns zero if there is an integer overflow. * tools/tiffcp.c (main): tiffcp should not leak memory if an error is reported when reading the input file.

|
* Revised: 2/18/01 BAR -- added syntax for extracting single images from
|
|
* multi-image TIFF files.
|
|
*
|
|
* New syntax is: sourceFileName,image#
|
|
*
|
|
* image# ranges from 0..<n-1> where n is the # of images in the file.
|
|
* There may be no white space between the comma and the filename or
|
|
* image number.
|
|
*
|
|
* Example: tiffcp source.tif,1 destination.tif
|
|
*
|
|
* Copies the 2nd image in source.tif to the destination.
