CVE-2023-38408
Severity CVSS v4.0:
Pending analysis
Type:
CWE-428
Unquoted Search Path or Element
Publication date:

Description
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.
