CVE-2023-38408

La característica PKCS#11 en ssh-agent en OpenSSH anterior a 9.3p2 tiene una ruta de búsqueda insuficientemente confiable, lo que lleva a la ejecución remota de código si un agente se reenvía a un sistema controlado por un atacante. (El código en /usr/lib no es necesariamente seguro para cargar en ssh-agent). NOTA: este problema existe debido a una solución incompleta para CVE-2016-10009.

A vulnerability was found in OpenSSH. The PKCS#11 feature in the ssh-agent in OpenSSH has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system (the code in /usr/lib is not necessarily safe for loading into ssh-agent). This flaw allows an attacker with control of the forwarded agent-socket on the server and the ability to write to the filesystem of the client host to execute arbitrary code with the privileges of the user running the ssh-agent.
