Affected packages

• PyPI Elixir: <= 0.7.1 (no fix yet)

Description

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.
