      "value": "ImageMagick is an open source software suite for displaying, converting, and editing raster image files. In ImageMagick versions prior to 7.1.2-7 and 6.9.13-32, an integer overflow vulnerability exists in the BMP decoder on 32-bit systems. The vulnerability occurs in coders/bmp.c when calculating the extent value by multiplying image columns by bits per pixel. On 32-bit systems with size_t of 4 bytes, a malicious BMP file with specific dimensions can cause this multiplication to overflow and wrap to zero. The overflow check added to address CVE-2025-57803 is placed after the overflow occurs, making it ineffective. A specially crafted 58-byte BMP file with width set to 536,870,912 and 32 bits per pixel can trigger this overflow, causing the bytes_per_line calculation to become zero. This vulnerability only affects 32-bit builds of ImageMagick where default resource limits for width, height, and area have been manually increased beyond their defaults. 64-bit systems with size_t of 8 bytes are not vulnerable, and systems using default ImageMagick resource limits are not vulnerable. The vulnerability is fixed in versions 7.1.2-7 and 6.9.13-32."

      "value": "ImageMagick es una suite de software de código abierto para mostrar, convertir y editar archivos de imagen ráster. En las versiones de ImageMagick anteriores a la 7.1.2-7 y 6.9.13-32, existe una vulnerabilidad de desbordamiento de entero en el decodificador BMP en sistemas de 32 bits. La vulnerabilidad ocurre en coders/bmp.c al calcular el valor de extensión multiplicando las columnas de la imagen por los bits por píxel. En sistemas de 32 bits con size_t de 4 bytes, un archivo BMP malicioso con dimensiones específicas puede causar que esta multiplicación se desborde y se ajuste a cero. La comprobación de desbordamiento añadida para abordar CVE-2025-57803 se coloca después de que ocurre el desbordamiento, lo que la hace ineficaz. Un archivo BMP de 58 bytes especialmente diseñado con un ancho establecido en 536,870,912 y 32 bits por píxel puede desencadenar este desbordamiento, haciendo que el cálculo de bytes_per_line se convierta en cero. Esta vulnerabilidad solo afecta a las compilaciones de 32 bits de ImageMagick donde los límites de recursos predeterminados para ancho, alto y área se han aumentado manualmente más allá de sus valores predeterminados. Los sistemas de 64 bits con size_t de 8 bytes no son vulnerables, y los sistemas que utilizan los límites de recursos predeterminados de ImageMagick no son vulnerables. La vulnerabilidad está corregida en las versiones 7.1.2-7 y 6.9.13-32."
