CVE-2010-3075

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.
