CVE-2026-93589

Description

A flaw was found in ImageMagick. This vulnerability, located in the FLIF encoder, is caused by an incorrect value for 'ticks per second' in an image being encoded. This can lead to a division-by-zero error, causing the encoder to crash and resulting in a denial of service, which means the software becomes unavailable.

Mitigation

To mitigate this issue, avoid processing untrusted FLIF image files with ImageMagick. If processing untrusted images is necessary, consider implementing sandboxing mechanisms to isolate ImageMagick operations and limit the potential 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.
