漏洞描述

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

解决建议

建议您更新当前系统或软件至最新版，完成漏洞的修复。
