  "message": "Fix integer overflow after recent change\n\nhttps://pdfium-review.googlesource.com/c/pdfium/+/134090 changed this\ncode to used signed integers. But signed integer overflow isn\u0027t\ndefined.\n\nSwitch to int64_t. THe products are int32_t * uint16_t, and we add\ntwo of those and one int32_t. This easily fits into an int64_t.\n\nThe first loop already naturally filters out very big and small\nx and y values.\n\nThe second does too as long as we let CJBig2_Image::Compose*()\ntake int64_ts, so switch to that.\n\nNo intended behavior change, except for fuzzer (and fuzzer-like)\ninputs.\n\nBug: 432691328\nChange-Id: I22ee3bb5306409eb9a965f254d534a9dca9caa39\nReviewed-on: https://pdfium-review.googlesource.com/c/pdfium/+/134470\nCommit-Queue: Nico Weber \u003cthakis@chromium.org\u003e\nReviewed-by: Lei Zhang \u003cthestig@chromium.org\u003e\nReviewed-by: Nico Weber \u003cthakis@google.com\u003e\n",
