Advisories for Maven/Pl.droidsonroids.gif/Android-Gif-Drawable package

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.

decoding.c in android-gif-drawable before 1.2.24 does not limit the maximum length of a comment, leading to denial of service.
