Descriptions

EncFS before 1.7.0 encrypts multiple blocks by means of the CFB cipher mode with the same initialization vector, which makes it easier for local users to obtain sensitive information via calculations involving recovery of XORed data, as demonstrated by an attack on encrypted data in which the last block contains only one byte.

EncFS anterior a v1.7.0 cifra varios bloques a través de el modo de cifrado CFB con el mismo vector de inicialización, lo cual hace más fácil para los usuarios locales obtener información sensible a través de los cálculos relativos a la recuperación de los datos XOR, como lo demuestra un ataque a los datos cifrados en el que el último bloque sólo contiene un byte.
