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)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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.
