  "message": "Fix some arithmetic nits in CBC_CommonBitMatrix.\n\n- make m_bits unsigned to avoid bitwise ops on signed values.\n- avoid possibility of UB with signed 1 shifted by 31.\n- limit total matrix size to avoid overflows.\n- avoid OOB writes in Set().\n\nChange-Id: I8b9f518af34e4ac9a1638f54523797014dc0bfe9\nReviewed-on: https://pdfium-review.googlesource.com/c/pdfium/+/90993\nReviewed-by: Lei Zhang \u003cthestig@chromium.org\u003e\nCommit-Queue: Tom Sepez \u003ctsepez@chromium.org\u003e\n",
