Description Andrej Nemec 2017-11-07 11:56:49 UTC
ReadGIFImage in coders/gif.c in ImageMagick 7.0.6-1 leaves the palette uninitialized when processing a GIF file that has neither a global nor local palette. If the affected product is used as a library loaded into a process that operates on interesting data, this data sometimes can be leaked via the uninitialized palette.
