Patch for bug #603081: failure to guard against bogus SamplesPerPixel
when converting a YCbCr image to RGB.
This patch duplicates into PickContigCase() a safety check that already
existed in PickSeparateCase().

Protect against a fax VL(n) codeword commanding a move left. Without
this, a malicious input file can generate an indefinitely large series
of runs without a0 ever reaching the right margin, thus overrunning
our buffer of run lengths. Per CVE-2011-0192. This is a modified
version of a patch proposed by Drew Yao of Apple Product Security.
It adds an unexpected() report, and disallows the equality case except
for the first run of a line, since emitting a run without increasing a0
still allows buffer overrun. (We have to allow it for the first run to
cover the case of encoding a zero-length run at start of line using VL.)

From f1c2759436a0ee5181cae7176114f57e45f0eb16 Mon Sep 17 00:00:00 2001

Subject: [PATCH] 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.

Make TIFFPrintDirectory cope with both TIFF_VARIABLE and TIFF_VARIABLE2
conventions for field_passcount fields, ie, either 16- or 32-bit counts.
This patch is taken from upstream commits dated 2012-05-23 ("fix crash
with odd 16bit count types for some custom fields") and 2012-12-12 ("Fix
TIFF_VARIABLE/TIFF_VARIABLE2 confusion in TIFFPrintDirectory").
This doesn't qualify as a security issue in itself, mainly because
TIFFPrintDirectory is unlikely to be used in any security-exposed
scenarios; but we need to fix it so that our test case for CVE-2012-5581
works on all platforms.

Using an array to clamp translated YCbCr values is insecure, because if the
TIFF file contains bogus ReferenceBlackWhite parameters, the computed RGB
values could be very far out of range (much further than the current array
size, anyway), possibly resulting in SIGSEGV. Just drop the whole idea in
favor of using a comparison-based macro to clamp. See RH bug #583081.
