AES Crypt is a file encryption software for multiple platforms. AES Crypt for Linux built using the source on GitHub and having the version number 3.11 has a vulnerability with respect to reading user-provided passwords and confirmations via command-line prompts. Passwords lengths were not checked before being read. This vulnerability may lead to buffer overruns. This does _not_ affect source code found on aescrypt.com, nor is the vulnerability present when providing a password or a key via the `-p` or `-k` command-line options. The problem was fixed via in commit 68761851b and will be included in release 3.16. Users are advised to upgrade. Users unable to upgrade should us the `-p` or `-k` options to provide a password or key.

The aescrypt gem 1.0.0 for Ruby does not randomize the CBC IV for use with the AESCrypt.encrypt and AESCrypt.decrypt functions, which allows attackers to defeat cryptographic protection mechanisms via a chosen plaintext attack.
