Remote Code Execution (RCE)

openssh is vulnerable to Remote Code Execution RCE. The vulnerability exists due to the insufficient trustworthy search path in the PKCS11 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...
