JLSEC-2026-925 ImageMagick (WriteBMPImage): 32-bit integer overflow when writing BMP scanline stride → heap buffer overflow

Summary A 32-bit integer overflow in the BMP encoder’s scanline-stride computation collapses bytesperline stride to a tiny value while the per-row writer still emits 3 × width bytes for 24-bpp images. The row base pointer advances using the overflowed stride, so the first row immediately writes...
