Summary
Elixir can leak information due to weak use of crypto
Details

Elixir prior to and including 0.7.1 uses Blowfish in CFB mode without constructing a unique initialization vector (IV), which makes it easier for context-dependent users to obtain sensitive information and decrypt the database. A patch has been attached to the initial advisory to mitigate this vulnerability.
