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 testing. This patch can go away once we no longer care about
|
||||
testing on pre-F18.

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.

|
||||
|
||||
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-2018-18557) 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)

Subject: [PATCH] (CVE-2022-3597 CVE-2022-3626 CVE-2022-3627) tiffcrop: disable
|
||||
incompatibility of -Z, -X, -Y, -z options with any PAGE_MODE_x option (fixes
|
||||
#411 and #413)

|
||||
|
||||
tiffcrop does not support –Z, -z, -X and –Y options together with any other PAGE_MODE_x options like -H, -V, -P, -J, -K or –S.
|
||||
|
||||
Code analysis:
|
||||
|
||||
With the options –Z, -z, the crop.selections are set to a value > 0. Within main(), this triggers the call of processCropSelections(), which copies the sections from the read_buff into seg_buffs[].
|
||||
In the following code in main(), the only supported step, where that seg_buffs are further handled are within an if-clause with if (page.mode == PAGE_MODE_NONE) .
|
||||
|
||||
Execution of the else-clause often leads to buffer-overflows.
|
||||
|
||||
Therefore, the above option combination is not supported and will be disabled to prevent those buffer-overflows.
|
||||
|
||||
The MR solves issues #411 and #413.
|
||||
|
||||

Subject: [PATCH] (CVE-2022-3599) Revised handling of TIFFTAG_INKNAMES and
|
||||
related TIFFTAG_NUMBEROFINKS value
|
||||
|
||||
In order to solve the buffer overflow issues related to TIFFTAG_INKNAMES and related TIFFTAG_NUMBEROFINKS value, a revised handling of those tags within LibTiff is proposed:
|
||||
|
||||
Behaviour for writing:
|
||||
`NumberOfInks` MUST fit to the number of inks in the `InkNames` string.
|
||||
`NumberOfInks` is automatically set when `InkNames` is set.
|
||||
If `NumberOfInks` is different to the number of inks within `InkNames` string, that will be corrected and a warning is issued.
|
||||
If `NumberOfInks` is not equal to samplesperpixel only a warning will be issued.
|
||||
|
||||
Behaviour for reading:
|
||||
When reading `InkNames` from a TIFF file, the `NumberOfInks` will be set automatically to the number of inks in `InkNames` string.
|
||||
If `NumberOfInks` is different to the number of inks within `InkNames` string, that will be corrected and a warning is issued.
|
||||
If `NumberOfInks` is not equal to samplesperpixel only a warning will be issued.
|
||||
|
||||
This allows the safe use of the NumberOfInks value to read out the InkNames without buffer overflow
|
||||
|
||||
This MR will close the following issues: #149, #150, #152, #168 (to be checked), #250, #269, #398 and #456.
|
||||
|
||||
It also fixes the old bug at http://bugzilla.maptools.org/show_bug.cgi?id=2599, for which the limitation of `NumberOfInks = SPP` was introduced, which is in my opinion not necessary and does not solve the general issue.
