Details

Dragonfly is an open source P2P-based file distribution and image acceleration system. Prior to 2.1.0, the first return value of a function is dereferenced even when the function returns an error. This can result in a nil dereference, and cause code to panic. This vulnerability is fixed in 2.1.0.
