5.0 MEDIUM — AV:N/AC:L/Au:N/C:P/I:N/A:N

Description

The blowfish mode in DAR before 2.3.4 uses weak Blowfish-CBC cryptography by (1) discarding random bits by the blowfish::make_ivec function in libdar/crypto.cpp that results in predictable and repeating IV values, and (2) direct use of a password for keying, which makes it easier for context-dependent attackers to decrypt files.

Affected configurations

• dar dar (<= 2.3.3)
