Descriptions

Use-after-free vulnerability in the GIFReadNextExtension function in lib/pngxtern/gif/gifread.c in OptiPNG 0.6.2 and earlier allows context-dependent attackers to cause a denial of service (application crash) via a crafted GIF image that causes the realloc function to return a new pointer, which triggers memory corruption when the old pointer is accessed.

Vulnerabilidad del tipo "use-after-free" (usar recurso después de haberlo liberado o destruido) en la función GIFReadNextExtension en lib/pngxtern/gif/gifread.c en OptiPNG v.0.6.2 y anteriores. Permite a atacantes dependientes del contexto causar una denegación del servicio (indisponibilidad y caída de la aplicación) a través de una imagen GIF manipulada que provoca que la llamada a la función realloc devuelva un nuevo puntero, que causa una corrupción de memoria cuando se accede al viejo puntero.
