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...

LowCVSS 2.1 EPSS 0.39%
SSL_Cipher.cpp in EncFS before 1.7.0 uses an improper combination of an AES cipher and a CBC cipher mode for encrypted filesystems, which allows local users to obtain sensitive information via a watermark attack.

LowCVSS 2.1 EPSS 0.71%
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.
