OpenSSL安全公告

　　OpenSSL发布了安全公告，发现1.0.1、1.0.2beta（包括1.0.1f和1.0.2beta1）版本存在【CVE-2014-0160】的高危漏洞，被SSL/TLS加密传输的信息可以被窃龋可行的方法就是尽快完成自查并升级到1.0.1g版本，避免因漏洞被黑客攻击而造成损失。下面是官方给的消息：

　　OpenSSL Security Advisory [07 Apr 2014]

　　========================================

　　TLS heartbeat read overrun (CVE-2014-0160)

　　==========================================

　　A missing bounds check in the handling of the TLS heartbeat extension can be

　　used to reveal up to 64k of memory to a connected client or server.

　　Only 1.0.1 and 1.0.2-beta releases of OpenSSL are affected including

　　1.0.1f and 1.0.2-beta1.

　　Thanks for Neel Mehta of Google Security for discovering this bug and to

　　Adam Langley <agl@chromium.org> and Bodo Moeller <bmoeller@acm.org> for

　　preparing the fix.

　　Affected users should upgrade to OpenSSL 1.0.1g. Users unable to immediately

　　upgrade can alternatively recompile OpenSSL with -DOPENSSL_NO_HEARTBEATS.

　　1.0.2 will be fixed in 1.0.2-beta2.

　　修复方案：

　　第一步： Debian/Ubuntu:

　　# apt-get update!

　　# apt-get install openssl libssl1.0.0

　　CentOS:

　　# yum update openssl

　　第二步： 修复完毕后,请重启WEB服务,Apache/Nginx/Httpd的重启⽅方式分别如下:

　　# /etc/init.d/apache2 restart

　　# /etc/init.d/ngnix restart

　　# /etc/init.d/httpd restart

　　此外还需要重启其他与OpenSSL相关的服务。(可通过 lsof | grep libssl | awk '{print $1}'| sort | uniq 查看与OpenSSL库相关的服务)。
