CVE-2023-38408 (GCVE-0-2023-38408)

Vulnerability from cvelistv5 – Published: 2023-07-20 00:00 – Updated: 2024-10-15 18:33

Summary

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.

Severity ?

9.8 (Critical)
