CVEID: CVE-2016-0778
DESCRIPTION: OpenSSH is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the packet_write_wait() and ssh_packet_write_wait() API functions when two non-default options: a ProxyCommand and either ForwardAgent or ForwardX11are used. By persuading a victim to connect to a malicious server, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
