<li> 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.
|
|
|
|
|
|
|
|
|
|
<li> 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
|
|
|
|
|
|
|
|
|
|
<li> 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.
