CVE-2026-56362 Details
Description
ImageMagick before 7.1.2-15 contains a heap-buffer-overflow read vulnerability in GetPixelIndex caused by OpenPixelCache updating image channel metadata before pixel cache memory allocation. Attackers can trigger memory and disk allocation failures to cause a heap-buffer-overflow read affecting any writer calling GetPixelIndex.
A heap-buffer-overflow read vulnerability has been identified in ImageMagick versions prior to 7.1.2-15 and 6.9.13-40. This vulnerability arises in the GetPixelIndex function, where the OpenPixelCache method updates image channel metadata before allocating memory for the pixel cache. Attackers can exploit this flaw by causing memory and disk allocation failures, leading to a heap-buffer-overflow read that affects any writer using GetPixelIndex.
Users can upgrade to ImageMagick versions 7.1.2-15 or 6.9.13-40 to address this vulnerability.
