Descriptions

SSL_Cipher.cpp in EncFS before 1.7.0 does not properly handle integer data sizes when constructing headers intended for randomization of initialization vectors, which makes it easier for local users to obtain sensitive information by defeating cryptographic protection mechanisms.

SSL_Cipher.cpp en EncFS anterior a v1.7.0 no maneja adecuadamente los tamaños de los datos enteros cuando construye cabeceras destinadas a la aleatorización de los vectores de inicialización, lo cual le hace más fácil a los usuarios locales obtener información sensible para superar la protección de mecanismos criptográficos.
