Kerentanan Unquoted Search Path or Element pada openbsd openssh, fedoraproject fedora. Skor CVSS 3.1 9.8 (Critical) menurut NVD.

Deskripsi (NVD)

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.
