- Fix CVE-2023-36664: Artifex Ghostscript through 10.01.2 mishandles
permission validation for pipe devices (with the %pipe% prefix or the |
pipe character prefix).
- Fix CVE-2023-38559: A buffer overflow flaw was found in
base/gdevdevn.c:1973 in devn_pcx_write_rle() in ghostscript. This
issue may allow a local attacker to cause a denial of service via
outputting a crafted PDF file for a DEVN device with gs.
- Fix CVE-2023-38560: An integer overflow flaw was found in
pcl/pl/plfont.c:418 in pl_glyph_name in ghostscript. This issue may
allow a local attacker to cause a denial of service via transforming a
crafted PCL file to PDF format.

PDF support was disabled in commit 7a4944569c (package/ghostscript:
bump to version 9.55.0) as it was then a new option which broke the
build.
PDF support depends on both openjpeg and jbig2dec. There is already a
conditional block for each, but it is not trivial to merge sanely, so we
introduce a third conditionl block to enable PDF. AS explained in the
comment, the dependencies are duplicated in that conditional block: in
case the other conditions get dropped in the future, we will still want
to depend on both for PDF support (unless that changes too, in which
case it will also be easier to spot and update).

Fix CVE-2022-2085: A NULL pointer dereference vulnerability was found in
Ghostscript, which occurs when it tries to render a large number of bits
in memory. When allocating a buffer device, it relies on an
init_device_procs defined for the device that uses it as a prototype
that depends upon the number of bits per pixel. For bpp > 64,
mem_x_device is used and does not have an init_device_procs defined.
This flaw allows an attacker to parse a large number of bits (more than
64 bits per pixel), which triggers a NULL pointer dereference flaw,
causing an application to crash.

The file access protection built into Ghostscript proved insufficient for
the "%pipe%" PostScript device, when combined with Ghostscript's requirement
to be able to create and control temporary files in the conventional
temporary file directories (for example, "/tmp" or "/temp). This exploit is
restricted to Unix-like systems (i.e., it doesn't affect Windows). The most
severe claimed results are only feasible if the exploit is run as a "high
privilege" user (root/superuser level) \u2013 a practice we would discourage
under any circumstances.

The ijs/ subfolder contains a bogus ltmain.sh file, which is actually a
broken symbolic link. Due to this, our logic to patch ltmain.sh files
fail with some patch versions:
>>> ghostscript 9.21 Patching libtool
File /home/buildroot/build/instance-0/output/build/ghostscript-9.21/ijs/ltmain.sh is not a regular file -- refusing to patch
Since we are anyway not using the ijs support (--without-ijs is passed),
do like we do for all other sub-components of ghostscript: get rid of
the ijs/ subfolder completely.
