ConnectBot SSH Client Library: Unbounded SSH field lengths can cause excessive memory allocation

Summary The SSH protocol parser trusted attacker-controlled length and count fields without first checking that the declared values fit within the containing packet. When a client connects to a malicious or compromised SSH server, the server can send a small, malformed packet containing an inner...
