CVE-2026-25794
ImageMagick is free and open-source software used for editing and manipulating digital images. `WriteUHDRImage` in `coders/uhdr.c` uses `int` arithmetic to compute the pixel buffer size. Prior to version 7.1.2-15, when image dimensions are large, the multiplication overflows 32-bit `int`, causing an undersized heap allocation followed by an out-of-bounds write. This can crash the process or potentially lead to an out of bounds heap write. Version 7.1.2-15 contains a patch.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H
- Puntuación base: 8.2
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.59%
- Percentil entre todas las CVEs puntuadas: 47
- Fecha de la puntuación: 6/10/2026
EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

'WriteUHDRImage' en 'coders/uhdr.c' utiliza aritmética de tipo 'int' para calcular el tamaño del búfer de píxeles. Antes de la versión 7.1.2-15, cuando las dimensiones de la imagen son grandes, la multiplicación desborda el tipo 'int' de 32 bits, lo que provoca una asignación de heap de tamaño insuficiente seguida de una escritura fuera de límites. Esto puede bloquear el proceso o potencialmente conducir a una escritura de heap fuera de límites. La versión 7.1.2-15 contiene un parche."
