漏洞名称:
受影响操作系统:桌面操作系统
危险等级:超危

发现日期:2023-09-27

漏洞描述

The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an incomplete fix for CVE-2016-10009.

修复方式

sudo apt update && sudo apt dist-upgrade

漏洞判定

执行命令apt policy PackageName获取软件包版本号，版本小于修复版本，则受此漏洞影响，版本大于等于修复版本，则此漏洞已修复
