A heap-buffer-overflow flaw was found in ImageMagick’s PushShortPixel() function of quantum-private.h file. This vulnerability is triggered when an attacker passes a specially crafted TIFF image file to ImageMagick for conversion, potentially leading to a denial of service.
### ImageMagick version

7.1.0-28

### Operating system

Linux

### Operating system, version and so on

### Description

Hello,
We found a heap overflow vulnerability in magick

### Steps to Reproduce

build it
`CC=afl-clang-lto CXX=afl-clang-lto++ CFLAGS="-g -fsanitize=address -fno-omit-frame-pointer" CXXFLAGS="-g -fsanitize=address -fno-omit-frame-pointer" LDFLAGS="-g -fsanitize=address -fno-omit-frame-pointer" ./configure --disable-shared --prefix="/root/fuzz/target/imagemagick/ImageMagick/install"`

`AFL_USE_ASAN=1 make -j24 && make install -j24`

run it
`./magick convert poc /dev/null`
output
