What is CVE-2016-10009?

The untrusted search path vulnerability in OpenSSH's ssh-agent component allows remote attackers to exploit control over a forwarded agent-socket. By manipulating this control, attackers can execute arbitrary local PKCS#11 modules. This can lead to unauthorized actions and compromise the security integrity of the system, as it bypasses typical safeguards in place for module execution.
