linux環(huán)境openssl、openssh升級(jí)流程
linux常因openssl、openssh漏洞進(jìn)行升級(jí)。
本文以u(píng)buntu22.04為例,對(duì)openssl、openssh進(jìn)行升級(jí)。
一.升級(jí)openssl
1.官網(wǎng)下載最新版openssl
wget https://www.openssl.org/source/openssl-3.0.15.tar.gz
如果因網(wǎng)絡(luò)原因下載不動(dòng),可以直接訪問(wèn)官網(wǎng),下載最新版本:
https://www.openssl.org/source/

2.安裝編譯環(huán)境
apt-get install -y build-essential
root@localhost:/opt/openssl-3.0.15# apt-get install -y build-essential Reading package lists... Done Building dependency tree... Done Reading state information... Done The following additional packages will be installed: bzip2 cpp cpp-11 dpkg-dev fakeroot fontconfig-config fonts-dejavu-core g++ g++-11 gcc gcc-11 gcc-11-base libalgorithm-diff-perl libalgorithm-diff-xs-perl libalgorithm-merge-perl libasan6 libatomic1 libc-dev-bin libc-devtools libc6-dev libcc1-0 libcrypt-dev libdeflate0 libdpkg-perl libfakeroot libfile-fcntllock-perl libfontconfig1 libgcc-11-dev libgd3 libgomp1 libisl23 libitm1 libjbig0 libjpeg-turbo8 libjpeg8 liblsan0 libmpc3 libnsl-dev libquadmath0 libstdc++-11-dev libtiff5 libtirpc-dev libtsan0 libubsan1 libwebp7 libxpm4 linux-libc-dev lto-disabled-list make manpages-dev rpcsvc-proto Suggested packages: bzip2-doc cpp-doc gcc-11-locales debian-keyring g++-multilib g++-11-multilib gcc-11-doc gcc-multilib autoconf automake libtool flex bison gdb gcc-doc gcc-11-multilib glibc-doc bzr libgd-tools libstdc++-11-doc make-doc
如果系統(tǒng)為CentOS,則執(zhí)行
yum install perl-IPC-Cmd perl-Data-Dumper gcc gcc-c++ perl perl-devel -y
3.下載后解壓安裝
tar -xf openssl-3.0.15.tar.gz -C /opt/
進(jìn)入目錄
cd /opt/openssl-3.0.15
編譯配置openssl安裝目錄
./config --prefix=/usr/local/openssl
root@localhost:~# tar -xf openssl-3.0.15.tar.gz -C /opt/ root@localhost:~# cd /opt/openssl-3.0.15/ root@localhost:/opt/openssl-3.0.15# ./config --prefix=/usr/local/openssl Configuring OpenSSL version 3.0.15 for target linux-x86_64 Using os-specific seed configuration Created configdata.pm Running configdata.pm Created Makefile.in Created Makefile Created include/openssl/configuration.h ********************************************************************** *** *** *** OpenSSL has been successfully configured *** *** *** *** If you encounter a problem while building, please open an *** *** issue on GitHub <https://github.com/openssl/openssl/issues> *** *** and include the output from the following command: *** *** *** *** perl configdata.pm --dump *** *** *** *** (If you are new to OpenSSL, you might want to consult the *** *** 'Troubleshooting' section in the INSTALL.md file first) *** *** *** **********************************************************************
安裝
make && make install
root@localhost:/opt/openssl-3.0.15# make && make install /usr/bin/perl "-I." -Mconfigdata "util/dofile.pl" "-oMakefile" include/crypto/bn_conf.h.in > include/crypto/bn_conf.h /usr/bin/perl "-I." -Mconfigdata "util/dofile.pl" "-oMakefile" include/crypto/dso_conf.h.in > include/crypto/dso_conf.h /usr/bin/perl "-I." -Mconfigdata "util/dofile.pl" "-oMakefile" include/openssl/asn1.h.in > include/openssl/asn1.h /usr/bin/perl "-I." -Mconfigdata "util/dofile.pl" "-oMakefile" include/openssl/asn1t.h.in > include/openssl/asn1t.h /usr/bin/perl "-I." -Mconfigdata "util/dofile.pl" "-oMakefile" include/openssl/bio.h.in > include/openssl/bio.h /usr/bin/perl "-I." -Mconfigdata "util/dofile.pl" "-oMakefile" include/openssl/cmp.h.in > include/openssl/cmp.h
4.備份更新openssl
備份openssl
mv /usr/bin/openssl /usr/bin/openssl_bak
復(fù)制openssl文件到/usr/bin/下
cp /usr/local/openssl/bin/openssl /usr/bin/
添加動(dòng)態(tài)鏈接庫(kù)數(shù)據(jù)
echo ‘/usr/local/openssl/lib64/' >> /etc/ld.so.conf
更新動(dòng)態(tài)鏈接庫(kù)
ldconfig
root@localhost:/opt/openssl-3.0.15# mv /usr/bin/openssl /usr/bin/openssl_bak root@localhost:/opt/openssl-3.0.15# cp /usr/local/openssl/bin/openssl /usr/bin/ root@localhost:/opt/openssl-3.0.15# echo "/usr/local/openssl/lib64/" >> /etc/ld.so.conf root@localhost:/opt/openssl-3.0.15# ldconfig
5.進(jìn)行驗(yàn)證
openssl version
root@localhost:/usr/local/openssl/lib64# openssl version OpenSSL 3.0.15 3 Sep 2024 (Library: OpenSSL 3.0.15 3 Sep 2024)
若出現(xiàn)如下問(wèn)題
root@localhost:/opt/openssl-3.0.15# openssl version openssl: /lib/x86_64-linux-gnu/libcrypto.so.3: version `OPENSSL_3.0.9' not found (required by openssl)
備份libcrypto.so.3文件后,復(fù)制安裝目錄下lib64/libcrypto.so.3到/lib/x86_64-linux-gnu/目錄
root@localhost:/opt/openssl-3.0.15# cd /usr/local/openssl/lib64/ root@localhost:/usr/local/openssl/lib64# ll total 16636 drwxr-xr-x 5 root root 4096 Jul 19 07:49 ./ drwxr-xr-x 7 root root 4096 Jul 19 07:50 ../ drwxr-xr-x 2 root root 4096 Jul 19 07:49 engines-3/ -rw-r--r-- 1 root root 9541222 Jul 19 07:49 libcrypto.a lrwxrwxrwx 1 root root 14 Jul 19 07:49 libcrypto.so -> libcrypto.so.3* -rwxr-xr-x 1 root root 5383824 Jul 19 07:49 libcrypto.so.3* -rw-r--r-- 1 root root 1268762 Jul 19 07:49 libssl.a lrwxrwxrwx 1 root root 11 Jul 19 07:49 libssl.so -> libssl.so.3* -rwxr-xr-x 1 root root 813928 Jul 19 07:49 libssl.so.3* drwxr-xr-x 2 root root 4096 Jul 19 07:49 ossl-modules/ drwxr-xr-x 2 root root 4096 Jul 19 07:49 pkgconfig/ root@localhost:/usr/local/openssl/lib64# mv /lib/x86_64-linux-gnu/libcrypto.so.3 /root/ root@localhost:/usr/local/openssl/lib64# cp libcrypto.so.3 /lib/x86_64-linux-gnu/ root@localhost:/usr/local/openssl/lib64# openssl version OpenSSL 3.0.15 3 Sep 2024 (Library: OpenSSL 3.0.15 3 Sep 2024)
二、升級(jí)openssh
1.下載最新版openssh
wget https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-9.9p1.tar.gz
如因網(wǎng)絡(luò)原因下載不動(dòng),可以直接訪問(wèn) ,下載最新版本https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/portable
2.安裝相關(guān)依賴
apt-get install -y zlib1g-dev libpam0g-dev
root@localhost:~# apt-get install -y zlib1g-dev libpam0g-dev Reading package lists... Done Building dependency tree... Done Reading state information... Done The following NEW packages will be installed: libpam0g-dev zlib1g-dev 0 upgraded, 2 newly installed, 0 to remove and 67 not upgraded. Need to get 281 kB of archives. After this operation, 1,010 kB of additional disk space will be used. Get:1 http://archive.ubuntu.com/ubuntu jammy-updates/main amd64 libpam0g-dev amd64 1.4.0-11ubuntu2.4 [117 kB] Get:2 http://archive.ubuntu.com/ubuntu jammy-updates/main amd64 zlib1g-dev amd64 1:1.2.11.dfsg-2ubuntu9.2 [164 kB] Fetched 281 kB in 2s (142 kB/s)
系統(tǒng)為CentOS,則執(zhí)行
yum install zlib-devel pam-devel -y
3.解壓安裝
tar xf openssh-9.9p1.tar.gz -C /opt/ cd /opt/openssh-9.9p1
配置安裝目錄
./configure --prefix=/usr/local/openssh –with-ssl-dir=/usr/local/openssl --sysconfdir=/etc/ssh --with-pam --with-gssapi --with-rsa --with-rhosts-allowed --with-zlib --with-md5-passwords
編譯安裝
make && make install
4.查看目錄版本
/usr/local/openssh/bin/ssh -V
root@localhost:/usr/local/openssh# ./bin/ssh -V OpenSSH_9.9p1, OpenSSL 3.0.15 3 Sep 2024
5.備份替換相關(guān)文件
mv /usr/sbin/sshd /usr/sbin/sshd_bak mv /usr/bin/ssh /usr/bin/ssh_bak mv /usr/bin/ssh-keygen /usr/bin/ssh-keygen_bak
cp -rf /usr/local/openssh/sbin/sshd /usr/sbin/sshd cp -rf /usr/local/openssh/bin/ssh /usr/bin/ssh cp -rf /usr/local/openssh/bin/ssh-keygen /usr/bin/ssh-keygen
6.重啟ssh服務(wù)
systemctl restart sshd
root@localhost:/usr/local/openssh# systemctl restart sshd.service root@localhost:/usr/local/openssh# ssh -V OpenSSH_9.9p1, OpenSSL 3.0.15 3 Sep 2024
執(zhí)行ssh服務(wù)狀態(tài)查詢命令
systemctl status sshd.service
查看發(fā)現(xiàn)文件的權(quán)限設(shè)置過(guò)于寬松
Permissions 0640 for'/etc/ssh/*****.key' are too open.
執(zhí)行chmod -R 600 /etc/ssh限制權(quán)限后重啟ssh服務(wù)
systemctl restart sshd
總結(jié)
以上為個(gè)人經(jīng)驗(yàn),希望能給大家一個(gè)參考,也希望大家多多支持腳本之家。
