Jumping into the thread without proper References: headers, since I was not subscribed before. Simon Thelen <foss-ml@...>: > Hello, > > When opening a gif file using giflib the RunningBits member of > GifFilePrivateType is never initialized before access in > DGifSetupDecompress (called from DGifGetImageDesc) causing the function > to occasionally set GifFile->Error = D_GIF_ERR_READ_FAILED and return > GIF_ERROR even though no actual error occurred. I was bitten by this in the image viewer that I use, sxiv: https://github.com/muennich/sxiv Since giflib 5.1.2, sxiv fails (variously "Corrupted gif image" and "Error opening image") when trying to view the _second_ gif, when given a list of images to view. giflib 5.1.1 does not have this problem. I can verify that the problem is solved with a giflib compiled from the repo at exactly ef0cb9b4be572262b49fbc26fb2348683f44a517 "Explicitly zero private storage.", which should be where the fix was pushed. Thanks for the fix Simon and Eric. I wish for a new release in the near future. //Daniel |
