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.","state":0,"publishedAt":"2025-10-17T16:30:27.144+00:00","modifiedAt":"2025-11-03T17:45:24.673+00:00","affected":[{"ecosystem":"Vendor product","name":"ImageMagick","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"ImageMagick\",\n                    \"product\": \"ImageMagick\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 6.9.13-32\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 7.0.0-0, < 7.1.2-7\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","score":5.9,"severity":"MEDIUM"}],"references":["https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-9pp9-cfwx-54rm","https://github.com/ImageMagick/ImageMagick/commit/cea1693e2ded51b4cc91c70c54096cbed1691c00"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-62171","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-62171","identifiers":["CVE-2025-62171"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
