Overview

openssl-encrypt is an A package for secure file encryption and decryption based on modern ciphers using heavy-compute-load chaining of hashing and KDF to generate strong encryption password based on users provided password to ensure secure encryption of files

Affected versions of this package are vulnerable to Eval Injection in the IsolatedPluginExecutor process when Python type objects are exposed in restricted exec() builtins. An attacker can execute arbitrary operating system commands by traversing the Python class hierarchy using __class__.__mro__.__subclasses__() to access system functions.
