CVE-2007-3528: Dar

Medium severity, CVSS 5.0. EPSS: 1.8% chance of exploitation in the next 30 days.

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 products

• Dar Dar: up to and including 2.3.3
