## Description

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.
