CVE-2026-24484
Description
A flaw was found in ImageMagick, a free and open-source software used for editing and manipulating digital images. A remote attacker could exploit this vulnerability by providing a specially crafted image file with multi-layer nested MVG (Magick Vector Graphics) conversions to SVG (Scalable Vector Graphics). This improper handling of conversions can lead to a Denial of Service (DoS), making the software unavailable to legitimate users.
Statement
This MODERATE impact denial of service vulnerability in ImageMagick affects Red Hat Enterprise Linux 6 ELS and 7 ELS, as well as Fedora and EPEL. The flaw occurs when converting multi-layer nested MVG files to SVG, where ImageMagick fails to properly validate the input, leading to resource exhaustion. Systems processing untrusted MVG files are susceptible to this issue.
Mitigation
Since this vulnerability involves processing untrusted image files, it is recommended to avoid converting multi-layer nested MVG files from untrusted sources to SVG format. Implement strict input validation and sanitization for any image files processed by ImageMagick. Additionally, consider running ImageMagick in a sandboxed environment to limit potential impact.
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.
