Does this matter?
Lower severity and a low EPSS score (1.76%). Track it; it rarely justifies an emergency change on its own.
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.
