This update for giflib fixes the following issues:
- CVE-2019-15133: Fixed a divide-by-zero exception in the decoder function DGifSlurp in dgif_lib.c if the height field of the ImageSize data structure is equal to zero (bsc#1146299).
- CVE-2018-11490: Fixed a heap-based buffer overflow in DGifDecompressLine function in dgif_lib.c (bsc#1094832).
- CVE-2016-3977: Fixed a heap buffer overflow in gif2rgb (bsc#974847).
Update to version 5.2.1
- In gifbuild.c, avoid a core dump on no color map.
- Restore inadvertently removed library version numbers in Makefile.
Changes in version 5.2.0
- The undocumented and deprecated GifQuantizeBuffer() entry point
has been moved to the util library to reduce libgif size and attack
surface. Applications needing this function are couraged to link the
util library or make their own copy.
- The following obsolete utility programs are no longer installed:
gifecho, giffilter, gifinto, gifsponge. These were either installed in
error or have been obsolesced by modern image-transformmation tools
like ImageMagick convert. They may be removed entirely in a future
release.
- Address SourceForge issue #136: Stack-buffer-overflow in gifcolor.c:84
- Address SF bug #134: Giflib fails to slurp significant number of gifs
- Apply SPDX convention for license tagging.
Changes in version 5.1.9

GIF89 standard, and a more detailed description of how LZW compression
is applied to GIFs.
