android openssl漏洞,nginx升级之openssl 漏洞

环境

1 之前是yum 安装的

2 centos 6.5

步骤

升级openssl

升级nginx

升级openssl

为了修补openssl低版本存在的漏洞，现将Centos 6.5系统openssl版本1.0.1e升级到1.1.0i(系统6.5-6.9都适用)，升级包括下载openssl-1.1.0i.tar.gz以及基础环境否则在"make"这一步会报错，故一定要安装zlib和zlib-devel

[root@ndsc ~]# yum -y install zlib zlib-devel

646 wget https://www.openssl.org/source/openssl-1.1.1g.tar.gz

647 ll

648 tar zxvf openssl-1.1.1g.tar.gz

649 cd openssl-1.1.1g

650 ./config shared zlib

651 make

652 ll

653 make install

654 mv /usr/bin/openssl /usr/bin/openssl.bak

655 find / -name openssl

656 cat /etc/ld.so.conf

657 echo "/usr/local/lib64/" >> /etc/ld.so.conf

658 cat /etc/ld.so.conf

659 ldconfig -v

660 openssl version

升级nginx

如果openssl 是静态编译的，直接将openssl 编译到nginx里面去了，这就意味着，单纯升级openssl 是没有任何效果的，nginx不会加载外部的openssl动态链接库的，必须将nginx重新编译。

nginx –V

如果编译参数中含有 –with-openssl= path ,或者有 –with-http_ssl_module ,则表明nginx 是静态编译的，那么恭喜你在升级完openssl 之后还有重新编译nginx，指定openssl 的目录。

# nginx -V

built with OpenSSL 1.0.1e-fips 11 Feb 2013

看到之前用的是openssl1.0.1需要升级

下载和之前一样的nginx版本

wget http://nginx.org/download/nginx-1.10.3.tar.gz

683 tar zxvf nginx-1.10.3.tar.gz

684 ll

685 cd nginx-1.10.3

686 ll

687 which nginx

688 ll /usr/sbin/nginx

689 nginx -V

看看之前的编译参数

备份一下之前的nginx程序

694 cp /usr/sbin/nginx /usr/sbin/nginxbak

按原来的重新编译

./configure --prefix=/usr/share/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --http-client-body-temp-path=/var/lib/nginx/tmp/client_body --http-proxy-temp-path=/var/lib/nginx/tmp/proxy --http-fastcgi-temp-path=/var/lib/nginx/tmp/fastcgi --http-uwsgi-temp-path=/var/lib/nginx/tmp/uwsgi --http-scgi-temp-path=/var/lib/nginx/tmp/scgi --pid-path=/var/run/nginx.pid --lock-path=/var/lock/subsys/nginx --user=nginx --group=nginx --with-file-aio --with-ipv6 --with-http_ssl_module --with-openssl --with-http_v2_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module=dynamic --with-http_image_filter_module=dynamic --with-http_geoip_module=dynamic --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_degradation_module --with-http_slice_module --with-http_stub_status_module --with-http_perl_module=dynamic --with-pcre --with-pcre-jit --with-stream=dynamic --with-stream_ssl_module --with-debug --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic' --with-ld-opt=' -Wl,-E'

编译时可能出现问题，百度一下安装下缺少的包就行

然后编译成功后注意千万不要make install

只要make 一下就行

然后把objs下的nginx复制到/usr/sbin，还有so文件替换一下 /usr/lib64/nginx/modules这里面的

cd /usr/lib64/nginx/

787 ll

788 cd modules/

789 ll

790 cd ..

791 cp -rp modules modulesbak

792 cd modules

793 cp -rp /opt/nginx-1.10.3/objs/*so .

最后停原来的nginx，启动新nginx

验证

python test.py xxxxx

看到likely not vulnerable,搞定了。
