CVE-2010-3075: EncFS before 1.7.0 encrypts multiple blocks by means of the CFB cipher mode with the same initialization ve...

Security readout for executives and security teams

EncFS versions before 1.7.0 had a cryptographic design flaw that reused an initialization value while encrypting multiple blocks. If a local user could access the encrypted data, the weakness could make it easier to infer sensitive plaintext. This is mainly a confidentiality risk for systems relying on old EncFS encryption. Exposure is most likely on legacy systems still using EncFS or fuse-encfs versions before 1.7.0, especially where multiple local users or services can read encrypted files. The source bundle does not identify other affected products. Treat as a legacy encryption hygiene issue. Prioritize if EncFS protects regulated, confidential, or customer data on shared systems. If EncFS is not deployed, business exposure is unlikely based on the provided sources. Mitigation focus: Upgrade EncFS or fuse-encfs to version 1.7.0 or a vendor-fixed package.; Check distribution advisories for the exact fixed package version.; Review whether sensitive data was encrypted with vulnerable EncFS versions..
