A double free vulnerability in the DDGifSlurp function in decoding.c in the android-gif-drawable library before version 1.2.18, as used in WhatsApp for Android before version 2.19.244 and many other Android applications, allows remote attackers to execute arbitrary code or cause a denial of service when the library is used to parse a specially crafted GIF image.
