CVE-2026-61869
Description
A flaw was found in ImageMagick. A memory leak in the Magick Image File Format (MIFF) encoder can occur when the software attempts to process an image and a memory allocation fails. This vulnerability allows an attacker to cause a denial of service (DoS) by exhausting system resources.
Statement
Red Hat Enterprise Linux ships ImageMagick in RHEL 6 ELS and RHEL 7 ELS. This flaw has been rated as having a Low security impact and is not currently planned to be addressed in future updates of those products. For additional information, refer to the Issue Severity Classification: https://access.redhat.com/security/updates/classification/.
Mitigation
Do not process untrusted image files with ImageMagick. The MIFF coder can be disabled in ImageMagick's policy.xml if not needed: `<policy domain="coder" rights="none" pattern="MIFF"/>`. Upgrade to ImageMagick 7.1.2-26 or 6.9.13-51 mitigates the issue.
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: Resource Consumption (Other)
When allocating resources without limits, an attacker could prevent other systems, applications, or processes from accessing the same type of resource. It can be easy for an attacker to consume many resources by rapidly making many requests or causing larger resources to be used than is needed.
