Last modified

CVE-2006-0591 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.38% chance of exploitation in the next 30 days.
