Description

[CVE-2012-2146] The 'acts_as_encrypted' feature of Elixir does not correctly initialize the random seed for the Blowfish encryption algorithm, and is therefore insecure. This option adds a new optional AES mode which does not suffer this problem, plus a warning is now printed when insecure Blowfish encryption is used.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
