CVE-2026-26283
Description
A flaw was found in ImageMagick. An attacker can exploit this vulnerability by providing a specially crafted image. This crafted image can trigger an infinite loop within the JPEG encoder, causing the software to consume 100% of the CPU and become unresponsive. This leads to a Denial of Service (DoS), preventing legitimate users from accessing the image processing functionality.
Statement
This MODERATE impact denial of service flaw in ImageMagick can be triggered by processing a specially crafted image, leading to an infinite loop and 100% CPU consumption. Red Hat Enterprise Linux 6 and 7, along with Fedora and EPEL, are affected by this vulnerability. Exploitation requires an attacker to provide a malicious image file to a system utilizing ImageMagick for image processing.
Mitigation
To mitigate this issue, avoid processing untrusted JPEG images with ImageMagick. If ImageMagick is deployed in a service context, consider implementing sandboxing mechanisms or restricting access to trusted sources to limit potential exposure.
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.

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Amplification
An infinite loop will cause unexpected consumption of resources, such as CPU cycles or memory. The software's operation may slow down, or cause a long time to respond.
