2018-05-03Invalidate GIF input buffer when moving file cursor backwardschromium/3420chromium/3419Ryan Harrison
The current implementation of the GIF codec does not handle the file cursor moving backwards correctly. Specifically the input buffer that the data is being read into is not invalidated, so if the entirity of the buffer hasn't been consumed, a chunk of it will be moved to the front before reading in more data, which is just incorrect. Additionally, depending on the specific series of operations, it is possible that the buffer was allocated for more space then had been read into it and the uninitialized portion at the end is being copied to the beginning. The file cursor may move backwards when dealing with an animated gif or other image with multiple frames, since all of the control data is read in on load, and future calls specify what frame to fetch. The code has been changed to treat the input buffer as invalid when moving the cursor to a frame location, which will bypass any of the problematic unused saving behaviour. A call to std::min has been added to prevent allocation of an input buffer larger then the file size. Additionally this CL refactors GifReadMoreData to be clearer about what calculations are occuring, since the existing code reuses a number of vaguely named variables, making it difficult to follow.
