CVE-2017-9935

In LibTIFF 4.0.8, there is a heap-based buffer overflow in the t2p_write_pdf
function in tools/tiff2pdf.c. This heap overflow could lead to different
damages. For example, a crafted TIFF document can lead to an out-of-bounds read
in TIFFCleanup, an invalid free in TIFFClose or t2p_free, memory corruption in
t2p_readwrite_pdf_image, or a double free in t2p_free. Given these
possibilities, it probably could cause arbitrary code execution.

Reproducers: tiff2pdf on the various files

BEFORE

12/tiff

$ valgrind -q tiff2pdf POCx -o out.pdf

[gives invalid reads]

11/tiff

$ valgrind -q tiff2pdf POCx -o out.pdf

[no valgrind issues observed]


PATCH:

12/tiff: needed
10sp3,11/tiff: needed after tiff2pdf.c update


AFTER

12/tiff

$ valgrind -q tiff2pdf POCx -o out.pdf

[no invalid reads anymore]

11/tiff

$ valgrind -q tiff2pdf POCx -o out.pdf

[still no valgrind issues]
