Hi, The following vulnerability was published for imagemagick. CVE-2025-62171[0]: | 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. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
