90
91        <li> tiffcrop: Added an option to allow the user to specify a
92        custom page size on the command line.  Fix the case where a
93        page size specified with a fractional part was being coerced
94        to an integer by retyping the variables that define the paper
95        size.  Corrected European page size dimensions.
96
97        <li> tiff2rgba: Completed fixes for "CVE-2009-2347 libtiff:
98        integer overflows in various inter-color space conversion
99        tools". http://bugzilla.maptools.org/show_bug.cgi?id=2079
100
101        <li> tiff2pdf: Fix assorted bugs in tiff2pdf: missing "return"
102        in t2p_read_tiff_size() causes t2p->tiff_datasize to be set entirely
103        wrong for COMPRESSION_JPEG case, resulting in memory stomp if actual
104        size is larger.  Also, there are a bunch of places that try to
105        memset() a malloc'd buffer before checking for malloc failure, which
106        would result in core dump if there actually were a failure.
