Loading vulnerability…
CVE-2016-0778 is a heap-based buffer overflow in the OpenSSH client’s roaming implementation, specifically in the roaming_read and roaming_write functions in roaming_common.c. It affects OpenSSH client versions 5.x, 6.x, and 7.x before 7.1p2. The flaw is triggered when the client connects to a malicious or compromised SSH server and certain proxy or forwarding-related options are enabled. Because the client does not properly maintain connection file descriptors during roaming-related processing, a hostile server can induce the client to request or process many forwardings in a way that corrupts heap memory. The documented result is denial of service, with the possibility of additional unspecified impact depending on memory corruption behavior.
