Vulnerability from github – Published: 2026-02-24 15:37 – Updated: 2026-02-24 15:37
VLAI?
Summary
ImageMagick has Division-by-Zero in YUV sampling factor validation, which leads to crash
Details

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.

coders/yuv.c:210:47: runtime error: division by zero
