An update that solves three vulnerabilities and has one fix can now be
installed.

## Description:

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

  * The documentation directory now includes an HTMlified version of the GIF89
    standard, and a more detailed description of how LZW compression is applied
    to GIFs.
  * Address SF bug #129: The latest version of giflib cannot be build on
    windows.
  * Address SF bug #126: Cannot compile giflib using c89

Changes in version 5.1.8

  * Address SF bug #119: MemorySanitizer: FPE on unknown address (CVE-2019-15133
    bsc#1146299)
  * Address SF bug #125: 5.1.7: xmlto is still required for tarball
  * Address SF bug #124: 5.1.7: ar invocation is not crosscompile compatible
  * Address SF bug #122: 5.1.7 installs manpages to wrong directory
  * Address SF bug #121: make: getversion: Command not found
  * Address SF bug #120: 5.1.7 does not build a proper library - no

Changes in version 5.1.7 * Correct a minor packaging error (superfluous
symlinks) in the 5.1.6 tarballs.

Changes in version 5.1.6 * Fix library installation in the Makefile.

Changes in version 5.1.5 * Fix SF bug #114: Null dereferences in main() of
gifclrmp * Fix SF bug #113: Heap Buffer Overflow-2 in function
DGifDecompressLine() in cgif.c. This had been assigned (CVE-2018-11490
bsc#1094832). * Fix SF bug #111: segmentation fault in PrintCodeBlock * Fix SF
bug #109: Segmentation fault of giftool reading a crafted file * Fix SF bug
#107: Floating point exception in giftext utility * Fix SF bug #105: heap buffer
overflow in DumpScreen2RGB in gif2rgb.c:317 * Fix SF bug #104: Ineffective
bounds check in DGifSlurp * Fix SF bug #103: GIFLIB 5.1.4: DGifSlurp fails on
empty comment * Fix SF bug #87: Heap buffer overflow in 5.1.2 (gif2rgb).
(CVE-2016-3977 bsc#974847) * The horrible old autoconf build system has been
removed with extreme prejudice. You now build this simply by running "make" from
the top-level directory.

The following non-security bugs were fixed:

  * build path independent objects and inherit CFLAGS from the build system
    (bsc#1184123)
