CVE-2023-38408 CRITICAL

Published: 2023-07-20 | Last Modified: 2024-11-21 | Status: Modified

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.

Additional Descriptions (1)

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.
