CVE-2026-26066
Description
A flaw was found in ImageMagick. A local attacker could provide a crafted image profile containing invalid IPTC (International Press Telecommunications Council) data. When ImageMagick attempts to write this data using the IPTCTEXT function, it may lead to an infinite loop, resulting in a Denial of Service (DoS) for the application.
Statement
This MODERATE impact flaw in ImageMagick can lead to a denial of service. A crafted profile containing invalid IPTC data may cause an infinite loop when ImageMagick attempts to write it with IPTCTEXT. Red Hat Enterprise Linux systems utilizing ImageMagick to process untrusted image files are affected.
Mitigation
To mitigate this issue, restrict ImageMagick's processing of untrusted image files. If ImageMagick is used in an automated or server-side context, consider implementing sandboxing mechanisms to limit the resources available to the ImageMagick process when handling external input. This can help contain the impact of a denial of service.
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.
