  "message": "Fix integer overflow in image size calculation\n\nGLsizei is historically defined as a 32-bit signed integer, which is\nnot allowed to be negative. But doing arithmetic with them can lead to\noverflows producing undefined values, including negative ones.\n\nUse size_t instead for these image data size calculations. It\u0027s defined\nas an unsigned integer large enough to fit valid memory buffer sizes.\nIn practice that\u0027s 32-bit on 32-bit platforms, and 64-bit on 64-bit\nones, which is large enough to avoid overflow in the OutOfMemory test.\n\nBug: b/140421004\nChange-Id: Id05dd64d470f579455fdc9925b0ab303ecaf37fb\nReviewed-on: https://swiftshader-review.googlesource.com/c/SwiftShader/+/36968\nTested-by: Nicolas Capens \u003cnicolascapens@google.com\u003e\nReviewed-by: Alexis Hétu \u003csugoi@google.com\u003e\n",
