  "message": "Avoid integer underflow in SkiaState::AdjustClip().\n\nWhen the current `m_clipIndex` is larger than the given `limit` index,\nSkiaState::AdjustClip() looks through the index range below the current\n`m_clipIndex` until it finds a save command to restore. If no save\ncommand is found, it reaches an assertion failure due to the index being\nnegative.\n\nThis CL makes sure `m_clipIndex` is non-negative when using it to access\nand check command types. If no save command is found, skip restoring\nand set `m_clipIndex` to 0, so that all commands below index `limit` can\nbe processed later. The added pixel test is a minimized version of the\nPDF that triggered the assertion failure in crbug.com/1116869.\n\nBug: chromium:1116869\nChange-Id: I47a71918c561c1cb121b91f929d3f0f60b3f22e9\nReviewed-on: https://pdfium-review.googlesource.com/c/pdfium/+/78570\nReviewed-by: Daniel Hosseinian \u003cdhoss@chromium.org\u003e\nCommit-Queue: Hui Yingst \u003cnigi@chromium.org\u003e\n",
