32764144 Security Vulnerability - heap buffer overflow in libgiftranscode.so
in colorMap->Colors[colorIndex]

* No range checking was done on a color index. Add range
checking and bail if the color index is out of range.

Test: tested sending a large gif that would invoke the GifTranscoder library
to make the gif smaller.
