CVE-2026-25799Network attack vector

Crash via invalid YUV sampling factor

Published Feb 24, 2026 · Updated Feb 24, 2026

Divide-by-zero in ImageMagick before 6.9.13-40 and 7.0.0 through 7.1.2-14 allows remote attackers to crash image-processing applications. ReadYUVImage in coders/yuv.c accepts an invalid YUV sampling factor because validation logic lets it pass, then uses the value as a divisor while loading the image. No authentication or interaction is required when a network-exposed application processes attacker-supplied YUV data; only process availability is affected.
