Doc Text:
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.

Description OSIDB Bzimport 2026-02-24 02:02:48 UTC
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a logic error in YUV sampling factor validation allows an invalid sampling factor to bypass checks and trigger a division-by-zero during image loading, resulting in a reliable denial-of-service. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
