CVE-2007-3528

UnknownEPSS 1.76%

Last modified

CVE-2007-3528 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.76% chance of exploitation in the next 30 days.
