Fedora 33: 2021-b349650e52 Critical: Gifsicle NULL Pointer Fix

Gifsicle is a command-line tool for creating, editing, and getting

information about GIF images and animations.

Some more gifsicle features:

* Batch mode for changing GIFs in place.

* Prints detailed information about GIFs, including comments.

* Control over interlacing, comments, looping, transparency...

* Creates well-behaved GIFs: removes redundant colors, only uses local

color tables if it absolutely has to (local color tables waste space

and can cause viewing artifacts), etc.

* It can shrink colormaps and change images to use the Web-safe palette

(or any colormap you choose).

* It can optimize your animations! This stores only the changed portion

of each frame, and can radically shrink your GIFs. You can also use

transparency to make them even smaller. Gifsicle?s optimizer is pretty

powerful, and usually reduces animations to within a couple bytes of

the best commercial optimizers.

* Unoptimizing animations, which makes them easier to edit.

* A dumb-ass name.

One other program is included with gifsicle

and gifdiff compares two GIFs for identical visual appearance.
