openssh is vulnerable to Remote Code Execution (RCE). The vulnerability exists due to the insufficient trustworthy search path in the PKCS#11 feature in ssh-agent of the library, allowing an attacker to inject and execute malicious code if an agent is forwarded to an attacker-controlled system. NOTE: this issue exists because of an incomplete fix for CVE-2016-10009.
