BClinux8.6 制作openssh9.2p2 rpm升级包和升级实战

一、背景说明

BClinux8.6 安装的openssh 版本为9.3p1,经绿盟扫描,存在高危漏洞,需要升级到最新。

OpenSSH 命令注入漏洞(CVE-2020-15778)   

OpenSSH 安全漏洞(CVE-2023-38408)

 目前官网只提供编译安装包,而BClinux8.6 为rpm方式安装。

为了方便升级,先通过编译安装包,制作rpm包,并进行升级

如下为做好的rpm升级包,可直接下载使用:

openssh 9.3p2 for bclinux & 龙蜥Anolis 8.6版本

1.1 系统版本查看 cat /etc/os-release

[root@localhost ~]# cat /etc/os-release

[root@localhost ~]# 

二、rpm包制作

2.1、安装制作的工具

dnf install rpm-build zlib-devel openssl-devel gcc perl-devel pam-devel libXt-devel gtk2-devel make perl -y

[root@localhost mysql]# dnf install rpm-build zlib-devel openssl-devel gcc perl-devel pam-devel  libXt-devel gtk2-devel make perl -y  
无法连接BC-Linux的YUM源服务器。
AppStream                                                                                                                                                                             176 kB/s | 4.3 kB     00:00

错误:没有任何匹配:  libXt-devel
[root@localhost mysql]# 

安装imake

dnf install imake  -y

##验证imake是否安装成功
[root@localhost mysql]# rpm -qa|grep imake
imake-1.0.7-11.el8.x86_64
[root@localhost mysql]# 

2.2下载源码

wget https://src.fedoraproject.org/repo/pkgs/openssh/x11-ssh-askpass-1.2.4.1.tar.gz/8f2e41f3f7eaa8543a2440454637f3c3/x11-ssh-askpass-1.2.4.1.tar.gz

wget https://mirrors.aliyun.com/pub/OpenBSD/OpenSSH/portable/openssh-9.3p2.tar.gz

2.3 初始化

##拷贝源码包到相应目录

mkdir -p /root/rpmbuild/SOURCES  
cp openssh-9.3p2.tar.gz /root/rpmbuild/SOURCES

cp x11-ssh-askpass-1.2.4.1.tar.gz /root/rpmbuild/SOURCES/  

##解压

[root@localhost ~]# cd rpmbuild/SOURCES/
[root@localhost SOURCES]# ls
openssh-9.3p2.tar.gz  x11-ssh-askpass-1.2.4.1.tar.gz
[root@localhost SOURCES]# tar -zxf openssh-9.3p2.tar.gz 

##解压源码包,拷贝spec文件

mkdir -p /root/rpmbuild/SPECS/  
   
[root@localhost openssh-9.3p2]# find ./ -name openssh.spec  
./contrib/redhat/openssh.spec
./contrib/suse/openssh.spec
[root@localhost openssh-9.3p2]#
[root@localhost openssh-9.3p2]# cp ./contrib/redhat/openssh.spec /root/rpmbuild/SPECS/

##尝试构建rpm包,提示报错:

[root@localhost SPECS]# rpmbuild -ba openssh.spec  
错误:构建依赖失败:  
        openssl-devel < 1.1 被 openssh-9.3p1-1.el8.bclinux.x86_64 需要  
[root@localhost SPECS]#

##解决方法

cd /root/rpmbuild/SPECS/  

vi openssh.spec  

注释如下行  

#BuildRequires: openssl-devel < 1.1 

2.4 rpm打包

再次执行成功:
rpmbuild -ba openssh.spec
等待编译完成

[root@localhost SPECS]# rpmbuild -ba openssh.spec

三、使用制作好的rpm包进行升级

3.1 升级前备份

##利用制作的rpm包对openssh进行升级
升级前检查rpm版本

[root@localhost SPECS]# rpm -qa|grep openssh  
openssh-clients-9.3p1-1.el8.bclinux.x86_64
openssh-9.3p1-1.el8.bclinux.x86_64
openssh-server-9.3p1-1.el8.bclinux.x86_64
[root@localhost SPECS]#

##备份配置文件
[root@localhost x86_64]# cp /etc/ssh/sshd_config /etc/ssh/sshd_config.20230806

##升级只需准备如下3个包
openssh-clients-9.3p2-1.el8.bclinux.x86_64.rpm openssh-9.3p2-1.el8.bclinux.x86_64.rpm openssh-server-9.3p2-1.el8.bclinux.x86_64.rpm

[root@localhost ~]# ls -lrt openssh-*
-rw-r--r-- 1 root root 670648 8月   6 10:03 openssh-clients-9.3p2-1.el8.bclinux.x86_64.rpm
-rw-r--r-- 1 root root 696820 8月   6 10:03 openssh-9.3p2-1.el8.bclinux.x86_64.rpm
-rw-r--r-- 1 root root 495228 8月   6 10:03 openssh-server-9.3p2-1.el8.bclinux.x86_64.rpm
[root@localhost ~]# 

3.2 开始升级dnf install *.rpm

[root@localhost ~]# dnf localinstall *.rpm
