一、给openssl-1.0.2u打包rpm

二、编译安装openssl-1.1.1k

三、给openssl-1.1.1k打包rpm（不推荐！）

近日openssl爆出拒绝服务、证书绕过漏洞，CVE编号CVE-2021-3449、CVE-2021-3450。

解决方法：
CentOS7默认openssl版本1.0.2，不受影响。
CentOS8默认openssl版本1.1.1，受影响，需要到OpenSSL1.1.1k及以上版本。

记录centos8编译打包openssl-1.0.2u、openssl-1.1.1k的过程。

一、给openssl-1.0.2u打包rpm

从官网https://www.openssl.org/source/old/1.0.2/下载openssl-1.0.2u.tar.gz，并做sha256校验。

cd rpmbuild/SOURCES/
wget https://www.openssl.org/source/old/1.0.2/openssl-1.0.2u.tar.gz
sha256sum ./openssl-1.0.2u.tar.gz
ecd0c6ffb493dd06707d38b14bb4d8c2288bb7033735606569d8f90f89669d16  ./openssl-1.0.2u.tar.gz

解压缩，把spec文件copy到SPEC目录下。

tar xvzf openssl-1.0.2u.tar.gz
cp openssl-1.0.2u/openssl.spec ../SPECS/openssl-1.0.2u.spec

编译打包openssl-1.0.2u并排错。报错Can't locate find.pl in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5，解决方案是安装依赖perl-Perl4-CoreLibs.noarch

rpmbuild -ba openssl-1.0.2u.specCan't locate find.pl in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5) at util/perlpath.pl line 7.

编译打包openssl-1.0.2u成功。

rpmbuild -ba --clean openssl-1.0.2u.spec

二、编译安装openssl-1.1.1k

从官网https://www.openssl.org/source/下载openssl-1.1.1k.tar.gz，并做sha256校验，再解压缩。

wget https://www.openssl.org/source/openssl-1.1.1k.tar.gzsha256sum ./openssl-1.1.1k.tar.gz
892a0875b9872acd04a9fde79b1f943075d5ea162415de3047c327df33fbaee5  ./openssl-1.1.1k.tar.gztar xvzf openssl-1.1.1k.tar.gz

编译安装
config生成Makefile
make编译，make test的结果一定要PASS
make install安装，或者其他选项只安装你需要的内容
如果在这些过程中提示有依赖项就安装，不OK就解决，再make clean后重新来过。

cd openssl-1.1.1k
./config
make
make test
make install

这样编译安装以后，openssl的版本升级到了1.1.1k，但是库文件仍使用原来1.1.1g版本的，不会影响使用。

openssl version
OpenSSL 1.1.1k  25 Mar 2021 (Library: OpenSSL 1.1.1g FIPS  21 Apr 2020)

三、给openssl-1.1.1k打包rpm（不推荐！动态库不兼容！）

这个包安装上以后，会导致严重的故障。

[root@test18 x86_64]# rpm --version
rpm: symbol lookup error: /lib64/librpmio.so.8: undefined symbol: EVP_md2, version OPENSSL_1_1_0[root@test18 x86_64]# yum remove openssl
Traceback (most recent call last):
......
ImportError: /lib64/libk5crypto.so.3: undefined symbol: EVP_KDF_ctrl, version OPENSSL_1_1_1b
......[root@test18 ~]# ldd /lib64/librpmio.so.8 | grep cryptolibcrypto.so.1.1 => /lib64/libcrypto.so.1.1 (0x00007f299ed70000)

原因是这种方式会替换库文件，不能替换这个库文件详细的原因在这个地方有https://github.com/openssl/openssl/issues/11471，请自行查看。

[root@test18 ~]# ll /lib64/libcrypto.so.1.1
lrwxrwxrwx. 1 root root 19 Dec 18 06:45 /lib64/libcrypto.so.1.1 -> libcrypto.so.1.1.1g

[root@test18 x86_64]# nm -gD /lib64/libcrypto.so.1.1 | grep EVP_KDF
Nothing！！！

这里只是记录编译打包的过程，不推荐使用！

从官网https://www.openssl.org/source/下载openssl-1.1.1k.tar.gz，并做sha256校验。解压缩，发现这个版本没有现成的spec文件。经查证在http://rpmfind.net/可以找到openssl-1.1.1g-12.el8.src.rpm这个包，这个包里面有1.1.1g版本的spec文件，可以找来使用。
该rpm文件cpio提取归档文件不会生成目录，因此建立一个目录存放，再下载。

mkdir openssl-1.1.1g-src
cd openssl-1.1.1g-src/
wget http://vault.centos.org/8.3.2011/BaseOS/Source/SPackages/openssl-1.1.1g-12.el8_3.src.rpm
rpm2cpio openssl-1.1.1g-12.el8_3.src.rpm | cpio -duim

提取的文件很多，把其中的openssl.spec拷贝到rpmbuild/SPECS目录下，并编辑openssl-1.1.1k.spec，修改源代码文件、版本、删除不需要的内容，最终形成openssl-1.1.1k.spec文件，内容如下。

# 0.9.6  soversion = 1
# 0.9.6a soversion = 2

# 0.9.7ef soversion = 5
# 0.9.8ab soversion = 6
# 0.9.8g soversion = 7
