修复Openssl FREAK(CVE-2015-0204)漏洞

March 24, 2015Comments

修复方法：

1:升级最新版本openssl，重新启动对应服务。#比如OpenSSL的1.0.1的用户应该升级到1.0.2
2：修改ssl加密算法：(nginx conf:ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;)
nginx修改为 ssl_ciphers HIGH:!aNULL:!MD5:!EXPORT56:!EXP;
httpd修改为 SSLCipherSuite HIGH:!aNULL:!MD5:!EXPORT56:!EXP
3：重新启动对应服务。文章源自 note.t4x.orgByrd's Blog-https://note.t4x.org/environment/fix-openssl-freak/
