This bumps libtiff's minor version from 9 to 10. In addition to the CVE
fixes that we already included this fixes:

CVE-2017-17095
CVE-2018-17101
CVE-2018-18557

The update is 100% backwards compatible, no symbol changes.

-Subject: [PATCH] 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] 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.

-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.
