MAJOR CHANGES:

- Complete the fixes for CVE-2009-2347.
- Tiffcrop now supports custom page sizes.

CHANGES IN THE SOFTWARE CONFIGURATION:

- None.

CHANGES IN LIBTIFF:

- Fixed inadequate validation of the SubjectDistance field.
- Fixed bad handling of out of order tags definated late by a codec.
- Avoid re-preparing jpeg tables unnecessarily.

CHANGES IN THE TOOLS:

- tiffcrop: Added an option to allow the user to specify a custom page size on the command line. Fix the case where a page size specified with a fractional part was being coerced to an integer by retyping the variables that define the paper size. Corrected European page size dimensions.
- tiff2rgba: Completed fixes for "CVE-2009-2347 libtiff: integer overflows in various inter-color space conversion tools". http://bugzilla.maptools.org/show_bug.cgi?id=2079
- tiff2pdf: Fix assorted bugs in tiff2pdf: missing "return" in t2p_read_tiff_size() causes t2p->tiff_datasize to be set entirely wrong for COMPRESSION_JPEG case, resulting in memory stomp if actual size is larger. Also, there are a bunch of places that try to memset() a malloc'd buffer before checking for malloc failure, which would result in core dump if there actually were a failure.

CHANGES IN THE CONTRIB AREA:

- None
