Detailsinfo

A vulnerability classified as critical has been found in ImageMagick up to 7.1.2-14. Affected is the function GetPixelIndex of the component Pixel Cache. The manipulation with an unknown input leads to a heap-based overflow vulnerability. CWE is classifying the issue as CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-56362 since 06/20/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Successful exploitation requires user interaction by the victim. Technical details are known, but there is no available exploit.
