What is CVE-2010-3075?
CVE-2010-3075 is a medium-severity vulnerability in n/a, published on 17 Sep 2010. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
Weakness: CWE-310
