CVE-2026-25971
Description
A flaw was found in ImageMagick, a free and open-source software for editing and manipulating digital images. This vulnerability occurs because ImageMagick fails to check for circular references between two Magick Scripting Language (MSL) files. A remote attacker could exploit this by providing specially crafted MSL files, leading to a stack overflow and ultimately a Denial of Service (DoS) condition, making the software unavailable.
Statement
This MODERATE impact vulnerability in ImageMagick arises from a stack overflow when processing maliciously crafted MSL files containing circular references. Red Hat Enterprise Linux and Community Projects are affected where ImageMagick is used to process untrusted image or script files.
Mitigation
To mitigate this issue, avoid processing untrusted or maliciously crafted MSL (Magick Scripting Language) files with ImageMagick. Implement strict input validation and sanitization for any ImageMagick operations that handle external or user-supplied content.
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.
