Summary

Dragonfly is an open source P2P-based file distribution and image acceleration system. Prior to 2.1.0, the DragonFly2 uses a variety of hash functions, including the MD5 hash, for downloaded files. This allows attackers to replace files with malicious ones that have a colliding hash. This vulnerability is fixed in 2.1.0.
