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.
