CVE-2026-25799

A flaw was found in ImageMagick, a free and open-source software used for editing and manipulating digital images. A logic error in the YUV sampling factor validation allows an invalid sampling factor to bypass security checks. This can trigger a division-by-zero error during image loading, leading to a reliable Denial of Service (DoS) for an affected system when processing a specially crafted image.

This MODERATE impact vulnerability in ImageMagick can lead to a denial-of-service. A logic error in YUV sampling factor validation allows an invalid sampling factor to bypass checks, triggering a division-by-zero during image loading.
