OpenSSH 安全漏洞
(CVE-2024-6387)
描述：OpenSSH（OpenBSD Secure Shell）是加拿大OpenBSD计划组的一套用于安全访问远程计算机的连接工具。该工具是SSH协议的开源实现，支持对所有的传输进行加密，可有效阻止窃听、连接劫持以及其他网络级的攻击。 OpenSSH 存在安全漏洞，该漏洞源于信号处理程序中存在竞争条件，攻击者利用该漏洞可以在无需认证的情况下远程执行任意代码并获得系统控制权。

介绍
# OpenSSH CVE-2024-6387
A vulnerability (CVE-2024-6387) has been discovered in OpenSSH. Successful exploitation of this vulnerability allows a remote, unauthenticated attacker to execute arbitrary code as root on the target machine.
All the glibc-based Linux distributions that have OpenSSH exposed are vulnerable to this issue.
## What should you do?
1. If you use virtual machines, bare-metal servers, or computers operating on Linux and accessible from the Internet, update firewall rules that may allow SSH through TCP on any port or limit the source IPs to trusted networks.
2. If OpenSSH needs to be left on, you can also execute a configuration update which eliminates the race case condition for the exploit. This is a runtime mitigation. To apply the changes in the sshd config, this script will restart the sshd service:
## Step by step:
1. Clone this repository
```
git clone https://github.com/rumochnaya/openssh-cve-2024-6387.sh.git
```
3. Open directory
```
cd openssh-cve-2024-6387.sh
```
5. Make a script executable
```
chmod +x openssh-cve-2024-6387.sh
```
6. Run the script
```
sudo ./openssh-cve-2024-6387.sh
```
## Done!
But be careful, update Linux at the first opportunity.
