- version update to 1.6.44:

Browse Source 
* Hardened calculations in chroma handling to prevent overflows, and
    relaxed a constraint in cHRM validation to accomodate the standard
    ACES AP1 set of color primaries.
    (Contributed by John Bowler)
  * Removed the ASM implementation of ARM Neon optimizations and updated
    the build accordingly. Only the remaining C implementation shall be
    used from now on, thus ensuring the support of the PAC/BTI security
    features on ARM64.
    (Contributed by Ross Burton and John Bowler)
  * Fixed the pickup of the PNG_HARDWARE_OPTIMIZATIONS option in the
    CMake build on FreeBSD/amd64. This is an important performance fix
    on this platform.
  * Applied various fixes and improvements to the CMake build.
    (Contributed by Eric Riff, Benjamin Buch and Erik Scholz)
  * Added fuzzing targets for the simplified read API.
    (Contributed by Mikhail Khachayants)
  * Fixed a build error involving pngtest.c under a custom config.
    This was a regression introduced in a code cleanup in libpng-1.6.43.
    (Contributed by Ben Wagner)
  * Fixed and improved the config files for AppVeyor CI and Travis CI.

From ceed2a3cf6af420a0782e7f6147d5965b01b772a Mon Sep 17 00:00:00 2001
From: John Bowler <jbowler@acm.org>
Date: Thu, 30 May 2024 07:53:42 -0700
Subject: [PATCH] SECURITY: disable build of filter_neon.S on arm
This fixes the bug https://github.com/pnggroup/libpng/issues/505
"libpng does not support PAC/BTI on aarch64 targets" which arises
because the build mechanisms (both cmake and configure) assemble
arm/filter_neon.S even though it ends up completely empty. The empty
file effectively poisons the so that the PAC/BTI support gets disabled.
The fix is minimal; it simply removes arm/filter_neon.S from the list of
sources included in the 64-bit ARM builds build. Note that this was
already done in cmake for MSVC - it's not clear whether this change was
a partial fix for the same issue.
This version of the fix ONLY affects aarch64 (arm64) builds; 32-bit ARM
systems can still invoke the assembler if required and, indeed, there
should be no change whatsover to those builds.
The assembler code could not be used on 64-bit systems in any case so
in practice there is no material change to 64-bit builds either.
TESTING: pull the changes then type "autoreconf" if using configure (not
required for cmake).
TESTS: cmake has not been tested because cross-builds with cmake
currently fail to find the zlib installation from the cmake system root
path. The following has been tested with configure cross builds:
armv7-linux-gnueabi [no neon support]
armv7a-linux-gnueabi [no neon support]
armv7a-hardfloat-linux-gnueabi [neon support not enabled]
armv7a-hardfloat-linux-gnueabi -mfpu=neon [uses intrinics]
armv7a-hardfloat-linux-gnueabi -mfpu=neon
-DPNG_ARM_NEON_IMPLEMENTATION=2 [uses assembler]
aarch64-linux-gnu [uses intrinsics]
aarch64-linux-gnu -DPNG_ARM_NEON_OPT=0 [neon support disabled]
