CVE-2006-0591 Detail

Current Description

The crypt_gensalt functions for BSDI-style extended DES-based and FreeBSD-sytle MD5-based password hashes in crypt_blowfish 0.4.7 and earlier do not evenly and randomly distribute salts, which makes it easier for attackers to guess passwords from a stolen password file due to the increased number of collisions.


View Analysis Description

Evaluator Description

This vulnerability may only be exploited in conjunction with another vulnerability. The password file (normally shadowed) must first be stolen.
