   An update that solves three vulnerabilities and has one
   errata is now available.

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)
