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 ... [Please see the references for more information on the vulnerabilities]");
