Subject: [PATCH] Back off the minimum required automake version to 1.11.
There isn't anything in libtiff currently that actually requires 1.12, and
changing this allows the package to be built on pre-F18 machines for easier

Subject: [PATCH] (CVE-2018-5784) Fix for bug 2772
It is possible to craft a TIFF document where the IFD list is circular,
leading to an infinite loop while traversing the chain. The libtiff
directory reader has a failsafe that will break out of this loop after
reading 65535 directory entries, but it will continue processing,
consuming time and resources to process what is essentially a bogus TIFF
document.
This change fixes the above behavior by breaking out of processing when
a TIFF document has >= 65535 directories and terminating with an error.

Subject: [PATCH] (CVE-2018-7456) Fix NULL pointer dereference in
TIFFPrintDirectory
The TIFFPrintDirectory function relies on the following assumptions,
supposed to be guaranteed by the specification:
(a) A Transfer Function field is only present if the TIFF file has
photometric type < 3.
(b) If SamplesPerPixel > Color Channels, then the ExtraSamples field
has count SamplesPerPixel - (Color Channels) and contains
information about supplementary channels.
While respect of (a) and (b) are essential for the well functioning of
TIFFPrintDirectory, no checks are realized neither by the callee nor
by TIFFPrintDirectory itself. Hence, following scenarios might happen
and trigger the NULL pointer dereference:
(1) TIFF File of photometric type 4 or more has illegal Transfer
Function field.
(2) TIFF File has photometric type 3 or less and defines a
SamplesPerPixel field such that SamplesPerPixel > Color Channels
without defining all extra samples in the ExtraSamples fields.
In this patch, we address both issues with respect of the following
principles:
(A) In the case of (1), the defined transfer table should be printed
safely even if it isn't 'legal'. This allows us to avoid expensive
checks in TIFFPrintDirectory. Also, it is quite possible that
an alternative photometric type would be developed (not part of the
standard) and would allow definition of Transfer Table. We want
libtiff to be able to handle this scenario out of the box.
(B) In the case of (2), the transfer table should be printed at its
right size, that is if TIFF file has photometric type Palette
then the transfer table should have one row and not three, even
if two extra samples are declared.
In order to fulfill (A) we simply add a new 'i < 3' end condition to
the broken TIFFPrintDirectory loop. This makes sure that in any case
where (b) would be respected but not (a), everything stays fine.
(B) is fulfilled by the loop condition
'i < td->td_samplesperpixel - td->td_extrasamples'. This is enough as
long as (b) is respected.
Naturally, we also make sure (b) is respected. This is done in the
TIFFReadDirectory function by making sure any non-color channel is
counted in ExtraSamples.
This commit addresses CVE-2018-7456.

Subject: [PATCH] (CVE-2017-9935) tiff2pdf: Fix CVE-2017-9935
Fix for http://bugzilla.maptools.org/show_bug.cgi?id=2704
This vulnerability - at least for the supplied test case - is because we
assume that a tiff will only have one transfer function that is the same
for all pages. This is not required by the TIFF standards.
We than read the transfer function for every page. Depending on the
transfer function, we allocate either 2 or 4 bytes to the XREF buffer.
We allocate this memory after we read in the transfer function for the
page.
For the first exploit - POC1, this file has 3 pages. For the first page
we allocate 2 extra extra XREF entries. Then for the next page 2 more
entries. Then for the last page the transfer function changes and we
allocate 4 more entries.
When we read the file into memory, we assume we have 4 bytes extra for
each and every page (as per the last transfer function we read). Which
is not correct, we only have 2 bytes extra for the first 2 pages. As a
result, we end up writing past the end of the buffer.
There are also some related issues that this also fixes. For example,
TIFFGetField can return uninitalized pointer values, and the logic to
detect a N=3 vs N=1 transfer function seemed rather strange.
It is also strange that we declare the transfer functions to be of type
float, when the standard says they are unsigned 16 bit values. This is
fixed in another patch.
This patch will check to ensure that the N value for every transfer
function is the same for every page. If this changes, we abort with an
error. In theory, we should perhaps check that the transfer function
itself is identical for every page, however we don't do that due to the
confusion of the type of the data in the transfer function.

Subject: [PATCH] (CVE-2018-8905) LZWDecodeCompat(): fix potential
index-out-of-bounds write. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2780 / CVE-2018-8905
The fix consists in using the similar code LZWDecode() to validate we
don't write outside of the output buffer.
(cherry picked from commit 58a898cb4459055bb488ca815c23b880c242a27d)

Subject: [PATCH] (CVE-2018-18557) JBIG: fix potential out-of-bounds write in
JBIGDecode()
JBIGDecode doesn't check if the user provided buffer is large enough
to store the JBIG decoded image, which can potentially cause out-of-bounds
write in the buffer.
This issue was reported and analyzed by Thomas Dullien.
Also fixes a (harmless) potential use of uninitialized memory when
tif->tif_rawsize > tif->tif_rawcc
And in case libtiff is compiled with CHUNKY_STRIP_READ_SUPPORT, make sure
that whole strip data is provided to JBIGDecode()

Subject: [PATCH] (CVE-2019-14973) Fix integer overflow in _TIFFCheckMalloc()
and other implementation-defined behaviour (CVE-2019-14973)
_TIFFCheckMalloc()/_TIFFCheckRealloc() used a unsafe way to detect overflow
in the multiplication of nmemb and elem_size (which are of type tmsize_t, thus
signed), which was especially easily triggered on 32-bit builds (with recent
enough compilers that assume that signed multiplication cannot overflow, since
this is undefined behaviour by the C standard). The original issue which lead to
this fix was trigged from tif_fax3.c
There were also unsafe (implementation defied), and broken in practice on 64bit
builds, ways of checking that a uint64 fits of a (signed) tmsize_t by doing
(uint64)(tmsize_t)uint64_var != uint64_var comparisons. Those have no known
at that time exploits, but are better to fix in a more bullet-proof way.
Or similarly use of (int64)uint64_var <= 0.

Subject: [PATCH] (CVE-2020-19131) tiffcrop.c: fix invertImage() for bps 2 and
4
too much bytes were processed, causing a heap buffer overrun
http://bugzilla.maptools.org/show_bug.cgi?id=2831
the loop counter must be
for (col = 0; col < width; col += 8 / bps)
Also the values were not properly calculated. It should be
255-x, 15-x, 3-x for bps 8, 4, 2.
But anyway it is easyer to invert all bits as 255-x = ~x, etc.
(substracting from a binary number composed of all 1 is like inverting
the bits)
