"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."

2.3.4 is in CVS for F-7+, FC-6 appears untreated at the moment.

Please mark the F-7 update as a security one in the updates system and add the
CVE reference to it (I have no permissions to do that).
