CVE-2023-38408  (opens in a new tab)
CWE-94  (opens in a new tab)

How to fix?

Upgrade Centos:9 openssh to version 0:8.7p1-30.el9_2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssh package and not the openssh package as distributed by Centos. See How to fix? for Centos:9 relevant fixed versions and status.

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.
