CVE-2023-1906: heap-buffer-overflow vulnerability in latest Imagemagick including 7.1.1-4 & 7.1.1-6 (Beta)
A heap-based buffer overflow issue was discovered in ImageMagick’s ImportMultiSpectralQuantum() function in MagickCore/quantum-import.c. An attacker could pass specially crafted file to convert, triggering an out-of-bounds read error, allowing an application to crash, resulting in a denial of service.
Summary
While fuzzing ImageMagick using AFL - We came across a heap overflow vulnerability which is vulnerable in 7.1.1-4,5&6.
