  "message": "Avoid 0 byte reads in ParseAndAppendCrossRefSubsectionData().\n\nThe existing CPDF_Parser::ParseAndAppendCrossRefSubsectionData() code\ndoes not handle reads properly when the read count is a multiple of the\nblock size. e.g. For a count of 2048 and a block size of 1024, it tries\nto read 1024, 1024, and 0 bytes.\n\nCommit cef91f11 added a check that causes 0 byte reads to fail, so the\nexisting behavior causes ParseAndAppendCrossRefSubsectionData() to fail\naltogether. Fix how ParseAndAppendCrossRefSubsectionData() loops to\navoid the 0 byte read.\n\nBUG\u003dchromium:945624\n\nChange-Id: Ie309dd6c3e139720f19962ec2a094512282aa8ed\nReviewed-on: https://pdfium-review.googlesource.com/c/pdfium/+/52410\nReviewed-by: Tom Sepez \u003ctsepez@chromium.org\u003e\nCommit-Queue: Lei Zhang \u003cthestig@chromium.org\u003e\n",
