openssh: Bounds check can be evaded in the shared memory manager used by pre-authentication compression support

It was found that the boundary checks in the code implementing support for pre-authentication compression could have been optimized out by certain compilers. An attacker able to compromise the privilege-separated process could possibly use this flaw for further attacks against the privileged...

openssh: Denial of service via very long passwords

It was found that OpenSSH did not limit password lengths for password authentication. A remote unauthenticated attacker could use this flaw to temporarily trigger high CPU consumption in sshd by sending long passwords...

openssh: Leak of host private key material to privilege-separated child process via realloc()

It was found that the host private key material could possibly leak to the privilege-separated child processes via re-allocated memory. An attacker able to compromise the privilege-separated process could therefore obtain the leaked key information...

SSH MITM - SSH Man-In-The-Middle Tool

This penetration testing tool allows an auditor to intercept SSH connections. A patch applied to the OpenSSH v7.5p1 source code causes it to act as a proxy between the victim and their intended SSH server; all plaintext passwords and sessions are logged to disk. Of course, the victim's SSH client...
