4Subject: [PATCH] * tools/tiff2rgba.c: Fix integer overflow in size of
5 allocated buffer, when -b mode is enabled, that could result in out-of-bounds
6 write. Based initially on patch tiff-CVE-2016-3945.patch from
7 libtiff-4.0.3-25.el7_2.src.rpm by Nikola Forro, with correction for invalid
8 tests that rejected valid files.

4Subject: [PATCH 1/2] Fix CVE-2016-9535
5
6* libtiff/tif_predict.h, libtiff/tif_predict.c: Replace
7 assertions by runtime checks to avoid assertions in debug mode, or buffer
8 overflows in release mode. Can happen when dealing with unusual tile size
9 like YCbCr with subsampling. Reported as MSVR 35105 by Axel Souchet &
10 Vishal Chauhan from the MSRC Vulnerabilities & Mitigations team.

12CVE: CVE-2016-9535
13Upstream-Status: Backport

10 MSVR 35096 and MSVR 35097. Discovered by Axel Souchet and Vishal Chauhan from

12 out-of-bounds write vulnerabilities in heap allocate buffer in
13 t2p_process_jpeg_strip(). Reported as MSVR 35098. Discovered by Axel Souchet
14 and Vishal Chauhan from the MSRC Vulnerabilities & Mitigations team. *
15 libtiff/tif_pixarlog.c: fix out-of-bounds write vulnerabilities in heap
16 allocated buffers. Reported as MSVR 35094. Discovered by Axel Souchet and
17 Vishal Chauhan from the MSRC Vulnerabilities & Mitigations team. *
18 libtiff/tif_write.c: fix issue in error code path of TIFFFlushData1() that
19 didn't reset the tif_rawcc and tif_rawcp members. I'm not completely sure if
20 that could happen in practice outside of the odd behaviour of t2p_seekproc()
21 of tiff2pdf). The report points that a better fix could be to check the
22 return value of TIFFFlushData1() in places where it isn't done currently, but
23 it seems this patch is enough. Reported as MSVR 35095. Discovered by Axel
24 Souchet & Vishal Chauhan & Suha Can from the MSRC Vulnerabilities &
