升级 python3

安装编译工具和依赖库

yum groupinstall -y "Development Tools"
yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel libpcap-devel xz-devel libffi-devel

下载Python 3的源码

wget https://www.python.org/ftp/python/3.7.17/Python-3.7.17.tgz

将上面的链接中的3.7.17替换为你想安装的Python版本号，例如3.8.0。

解压源码包

tar xvf Python-3.7.17.tgz

编译安装

cd Python-3.7.17
./configure --enable-optimizations
make
make altinstall

使用altinstall是为了避免覆盖系统默认的Python版本。

拷贝包到新python的包中

cp -rnp /usr/lib/python3.7/site-packages/* /usr/local/lib/python3.7/site-packages/
cp -rnp /usr/lib64/python3.7/site-packages/* /usr/local/lib/python3.7/site-packages/

更新Python链接

mv /usr/bin/python3{,.bak}
ln -s /usr/local/bin/python3.7 /usr/bin/python3

验证安装

python3 --version
python3.7 --version

漏洞

python CVE-2023-27043

Python 2.7.18 不需升级 Python 3.7.9 升级至 3.7.17

vsftpd升级到3.0.5(或者直接安装)

(参考地址)[https://blog.csdn.net/hhq850741642/article/details/140723077]

下载vsftpd源码

wget https://security.appspot.com/downloads/vsftpd-3.0.5.tar.gz

卸载原vsftpd

# 备份原配置文件
cp -rnp /etc/vsftpd{,.ljh.202410301611}
cp -rnp /etc/pam.d/vsftpd{,.ljh.202410301611}
# 卸载原vsftpd
systemctl stop vsftpd.service
yum remove -y vsftpd

编译vsftpd源码

64位的系统编译之前先要执行 cp /lib64/libcap.so.1 /lib/libcap.so.1 命令：

注：这里并没有用到

yum groupinstall -y "Development Tools"
yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel libpcap-devel xz-devel libffi-devel
yum install -y libcap-devel
tar xzvf vsftpd-3.0.5.tar.gz
cd vsftpd-3.0.5
# 替换文件内容，因为是手动安装的，需要变更文件地址
sed -i 's#/etc/vsftpd.#/etc/vsftpd/#g' tunables.c
sed -i 's#/etc/vsftpd.conf#/etc/vsftpd/vsftpd.conf#g' defs.h
make
make install

配置文件(新安装)

vsftpd.conf

# Example config file /etc/vsftpd/vsftpd.conf
#
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.
#
# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
# capabilities.
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
anonymous_enable=NO
#
# Uncomment this to allow local users to log in.
local_enable=YES
#
# Uncomment this to enable any form of FTP write command.
write_enable=YES
#
# Default umask for local users is 077. You may wish to change this to 022,
# if your users expect that (022 is used by most other ftpd's)
local_umask=022
#
# Uncomment this to allow the anonymous FTP user to upload files. This only
# has an effect if the above global write enable is activated. Also, you will
# obviously need to create a directory writable by the FTP user.
# When SELinux is enforcing check for SE bool allow_ftpd_anon_write, allow_ftpd_full_access
#anon_upload_enable=YES
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
#anon_mkdir_write_enable=YES
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.
dirmessage_enable=YES
#
# Activate logging of uploads/downloads.
xferlog_enable=YES
#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=YES
#
# If you want, you can arrange for uploaded anonymous files to be owned by
# a different user. Note! Using "root" for uploaded files is not
# recommended!
#chown_uploads=YES
#chown_username=whoever
#
# You may override where the log file goes if you like. The default is shown
# below.
#xferlog_file=/var/log/xferlog
#
# If you want, you can have your log file in standard ftpd xferlog format.
# Note that the default log file location is /var/log/xferlog in this case.
xferlog_std_format=YES
#
# You may change the default value for timing out an idle session.
#idle_session_timeout=600
#
# You may change the default value for timing out a data connection.
#data_connection_timeout=120
#
# It is recommended that you define on your system a unique user which the
# ftp server can use as a totally isolated and unprivileged user.
#nopriv_user=ftpsecure
#
# Enable this and the server will recognise asynchronous ABOR requests. Not
# recommended for security (the code is non-trivial). Not enabling it,
# however, may confuse older FTP clients.
#async_abor_enable=YES
#
# By default the server will pretend to allow ASCII mode but in fact ignore
# the request. Turn on the below options to have the server actually do ASCII
# mangling on files when in ASCII mode. The vsftpd.conf(5) man page explains
# the behaviour when these options are disabled.
# Beware that on some FTP servers, ASCII support allows a denial of service
# attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
# predicted this attack and has always been safe, reporting the size of the
# raw file.
# ASCII mangling is a horrible feature of the protocol.
#ascii_upload_enable=YES
#ascii_download_enable=YES
#
# You may fully customise the login banner string:
#ftpd_banner=Welcome to blah FTP service.
#
# You may specify a file of disallowed anonymous e-mail addresses. Apparently
# useful for combatting certain DoS attacks.
#deny_email_enable=YES
# (default follows)
#banned_email_file=/etc/vsftpd/banned_emails
#
# You may specify an explicit list of local users to chroot() to their home
# directory. If chroot_local_user is YES, then this list becomes a list of
# users to NOT chroot().
# (Warning! chroot'ing can be very dangerous. If using chroot, make sure that
# the user does not have write access to the top level directory within the
# chroot)
#chroot_local_user=YES
#chroot_list_enable=YES
# (default follows)
#chroot_list_file=/etc/vsftpd/chroot_list
#
# You may activate the "-R" option to the builtin ls. This is disabled by
# default to avoid remote users being able to cause excessive I/O on large
# sites. However, some broken FTP clients such as "ncftp" and "mirror" assume
# the presence of the "-R" option, so there is a strong case for enabling it.
#ls_recurse_enable=YES
#
# When "listen" directive is enabled, vsftpd runs in standalone mode and
# listens on IPv4 sockets. This directive cannot be used in conjunction
# with the listen_ipv6 directive.
listen=NO
#
# This directive enables listening on IPv6 sockets. By default, listening
# on the IPv6 "any" address (::) will accept connections from both IPv6
# and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6
# sockets. If you want that (perhaps because you want to listen on specific
# addresses) then you must run two copies of vsftpd with two configuration
# files.
# Make sure, that one of the listen options is commented !!
listen_ipv6=YES

pam_service_name=vsftpd
