openssl 升级到OpenSSL 1.0.1g 修复HEARTBEATS漏洞
CentOS 6.4 64位
查看当前的ssl版本
[root@localhost ~]# ssh -V OpenSSH_5.3p1, OpenSSL 1.0.0-fips 29 Mar 2010
升级openssl
升级前请关闭selinux
yum install zlib zlib-devel krb5-devel.x86_64 -y wget http://www.openssl.org/source/openssl-1.0.1g.tar.gz tar -xzf openssl-1.0.1g.tar.gz cd openssl-1.0.1g ./config --prefix=/usr/local/ssl shared zlib-dynamic enable-camellia -DOPENSSL_NO_HEARTBEATS #添加 -DOPENSSL_NO_HEARTBEATS 选项 make make install openssl version mv /usr/bin/openssl /usr/bin/openssl.old mv /usr/include/openssl /usr/include/opensslold ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl ln -s /usr/local/ssl/include/openssl/ /usr/include/openssl echo "/usr/local/ssl/lib/" >> /etc/ld.so.conf ldconfig -v|grep ssl openssl version
升级后截图
openssl version -a
为什么升级openssh，因为用xshell或者SecureCRT等终端连接服务器是用ssh，现在查看ssh所用openssl所用的版本还是这样的
[root@localhost ~]# ssh -V OpenSSH_5.3p1, OpenSSL 1.0.0-fips 29 Mar 2010
验证：
# rpm -qa openssl
openssl-1.0.1e-16.el6_5.14.x86_64
# rpm -q --changelog openssl-1.0.1e | grep CVE-2014-0160
- fix CVE-2014-0160 - information disclosure in TLS heartbeat extension
说明漏洞已经修复
升级 openssh （编译时候请按文章最下面，添加--with-kerberos5=/usr/lib64/libkrb5.so 参数编译，不然会出现下面的问题）
wget http://mirror.internode.on.net/pub/OpenBSD/OpenSSH/portable/openssh-6.6p1.tar.gz yum install pam* tar -xzf openssh-6.6p1.tar.gz cd openssh-6.6p1 ./configure --prefix=/usr --sysconfdir=/etc/ssh --with-pam --with-zlib --with-ssl-dir=/usr/local/ssl --with-md5-passwords --mandir=/usr/share/man make make install ssh -V OpenSSH_6.6p1, OpenSSL 1.0.1g 7 Apr 2014 service sshd restart 停止 sshd： [确定] 正在启动 sshd： [确定]
升级完成后打开新的终端连接
升级完成
当执行service sshd restart 的时候有错误提示
vim /etc/ssh/sshd_config 把81和83行注释
再执行就没问题了
service sshd restart Stopping sshd: [ OK ] Starting sshd: [ OK ]
附：
Unsupported option GSSAPIAuthentication 和 Unsupported option GSSAPICleanupCredentials
这两个认证机制的解决方法：
service sshd restart Stopping sshd: [ OK ] Starting sshd: /etc/ssh/sshd_config line 81: Unsupported option GSSAPIAuthentication /etc/ssh/sshd_config line 83: Unsupported option GSSAPICleanupCredentials [ OK ]
在编译openssh-6.6p1的时候把kerberos5的选项指定，即添加选项 --with-kerberos5=/usr/lib64/libkrb5.so 就不会出现问题
[root@localhost openssh-6.6p1]# ./configure --prefix=/usr --sysconfdir=/etc/ssh --with-pam --with-zlib --with-ssl-dir=/usr/local/ssl --with-md5-passwords --mandir=/usr/share/man --with-kerberos5=/usr/lib64/libkrb5.so
下面是sshd_config的配置文件，认证不受影响的，重启sshd服务也没问题
vim /etc/ssh/sshd_config
上述的代码
升级前关闭selinux
升级ssl，ssh
yum install zlib zlib-devel -y
yum install krb5-devel.x86_64 -y
wget http://www.openssl.org/source/openssl-1.0.1g.tar.gz
tar -xzf openssl-1.0.1g.tar.gz
cd openssl-1.0.1g
./config --prefix=/usr/local/ssl shared zlib-dynamic enable-camellia -DOPENSSL_NO_HEARTBEATS
make
make install
openssl version
mv /usr/bin/openssl /usr/bin/openssl.old
mv /usr/include/openssl /usr/include/opensslold
ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl
ln -s /usr/local/ssl/include/openssl/ /usr/include/openssl
echo "/usr/local/ssl/lib/" >>/etc/ld.so.conf
ldconfig -v|grep ssl
openssl version

cd openssh-6.6p1
./configure --prefix=/usr --sysconfdir=/etc/ssh --with-pam --with-zlib --with-ssl-dir=/usr/local/ssl --with-md5-passwords --mandir=/usr/share/man --with-kerberos5=/usr/lib64/libkrb5.so
