CVE-2026-109261

Description

A flaw was found in ImageMagick. A remote attacker can cause a Denial of Service (DoS) by providing specially crafted images for GIF conversion that cause color quantization to fail. Because allocated memory is not freed when this failure occurs, repeated processing requests continuously leak memory, degrading system performance and potentially causing the service to become unavailable.

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.
