CVE-2026-56368
Description
A flaw was found in ImageMagick. This memory leak vulnerability exists in multiple coders that write raw pixel data, where allocated objects are not properly freed. A remote attacker can exploit this by processing specially crafted images, leading to memory exhaustion and a denial of service.
Statement
A memory leak exists in ImageMagick's raw pixel data coders. Processing specially crafted, untrusted images can exhaust system memory and cause a Denial of Service (DoS).
Mitigation
Modify the ImageMagick security policy file (policy.xml, typically located in /etc/ImageMagick-7/ or /etc/ImageMagick-6/) to disable the processing of RAW pixel data formats.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
