Comment 2 for bug 1580376

Both 5.1.3 and 5.1.4 are bug fix releases:

+Version 5.1.4
+=============
+
+Code Fixes
+----------
+
+* Fix SF bug #94: giflib 5 loves to fail to load images... a LOT.
+
+* Fix SF Bug #92: Fix buffer overread in gifbuild.
+
+* Fix SF Bug #93: Add bounds check in gifbuild netscape2.0 path
+
+* Fix SF Bug #89: Fix buffer overread in gifbuild.
+
+Version 5.1.3
+=============
+
+As of this version the library and code has been seriously abused by fuzzers,
+smoking out crash bugs (now fixed) induced by various kinds of severely
+malformed GIF.
+
+Code Fixes
+----------
+
+* Prevent malloc randomess from causing the header output routine to emit
+ a GIF89 version string even when no GIF89 features are present. Only
+ breaks tests, not production code, but it's odd this wasn't caught sooner.
+
+* Prevent malloc randomess from producing sporadic failures by causing
+ sanity checks added in 5.1.2 to misfire.
+
+* Bulletproof gif2rgb against 0-height images. Addressed SF bug #78:
+ Heap overflow in gif2rgb with images of size 0, also SF bug #82.
+
+* Remove unnecessary duplicate EGifClose() in gifcolor.c. Fixes SF bug #83
+ introduced in 5.1.2.
+
+* Fix SF Bug #84: incorrect return of DGifSlurp().
