[Debian] Critical CVE: CVE-2023-38408 openssh: an insufficiently trustworthy search path

[Yue Tao]

CVE-2023-38408: https://nvd.nist.gov/vuln/detail/CVE-2023-38408

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.

Base Score: Critical
