CVE-2007-3528  (opens in a new tab)

How to fix?

Upgrade Debian:12 dar to version 2.3.3-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream dar package and not the dar package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

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.
