Fixes the following vulnerability:
- CVE-2025-62171
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.
