Gif coder leaves the palette uninitialized if neither global nor local palette is present in a gif file. If ImageMagick is used as a library loaded into a process that operates on interesting data, this can cause security consequences.
Repro is available at https://gist.githubusercontent.com/neex/8df05383c58abfea388fdc867a197418/raw/e1bb77c3497420fdd1bcd539ca08fbabd5dfa23f/sample.gif.
